<p>The first objective of this study is to show if diffusion of contraception in areas of traditional high fertility has gone through profound changes. Indeed, we would like to know if contraceptive behaviours have evolved because of new fertility perceptions and also because partners now have greater freedom to make choices in a relationship. The second objective of this study is not only to highlight the levels and trends of contraception and the factors influencing their use (government policies, role of family planning, etc.) in developing countries, but also to consider the population of unmet-needs of contraception. Indeed, the level of contraceptive use depends obviously on users, but also on non-users with no needs and non-users with unsatisfied needs. The understanding of this last category of females is essential to a more accurate estimation of contraception levels, and, therefore for the estimation of fertility levels. This study analyses the contraceptive use in several developing countries in Africa and highlights the unsatisfied needs of contraception, to understand why such needs exist. To do so, we shall analyse available demographic data for thirty-five African countries by using the available Demographic and Health Surveys (DHS), from the 1980&rsquo / s to 2000&rsquo / s considering the DHS I, DHS II, DHS III and DHS IV. This great variety of surveys, seventy-nine in total, permits one to compare levels of contraception and &ldquo / unmet-needs&rdquo / from country to country. The surveys also, make it possible to compare the evolution over time of specific countries or specific regions, and to subsequently comprehend the determining factors of contraceptive use or non-use.</p>

<p>Background: About 22.4 million people were living with HIV/AIDS in 2008 out of which women constitute approximately 57%. Namibia is one of the highly affected countries with a national HIV prevalence of 17.8% among women attending antenatal clinics. Antiretroviral medications have become available in Namibia since 2002 and presently all district hospitals and some health centres provide ARVs to those in need. Namibia is rated as one of the few countries in sub-Sahara Africa with a high coverage of ART, with 80% of those in need of ART receiving the treatment. An increasing trend has been observed whereby HIV+ women on ARV are becoming pregnant. Little is known about the attitude, knowledge and behavior of these women towards family planning and use of contraceptives and what barriers they may be facing in accessing these services.Aim: To determine the factors affecting the utilization of family planning services by HIV+ pregnant women receiving PMTCT services. Methodology: The study was a cross sectional study using both quantitative and qualitative methods to assess the critical elements of knowledge, attitude and perceptions of the study participants towards family planning services. The study also assessed the health system and other factors that impact on the use of contraceptives by HIV+ women. It was conducted in northern Namibia at Oshakati Health centre among randomly selected pregnant HIV+ women attending for PMTCT services.Results: Among the 113 respondents, who participated in the study, 97.3% knew at least one method of family planning but only 53.6% actually used any method of contraception prior to current pregnancy. Among the 46.4% who did not use any contraception, the reasons often cited for non-use were because they wanted a baby (52%), spouse objection (10%), being afraid of the effects (14%) and other reasons such as belief, culture and distance to travel to the health facility. 88% of the respondents indicated a willingness to use contraceptives after current pregnancy and expressed general satisfaction with services at the health centre while asking for more information on family planning services.Conclusion: HIV+ women have high awareness on some contraceptives but use of contraceptives is not as high as many of them have a desire to have children for self esteem and leave a legacy for the future. Knowledge of the risks of pregnancy on HIV+ woman may be limited and there is a need to improve educational intervention in this regard as well as integrate family planning services into all HIV/AIDS services.</p>

This study investigated attitudes toward personal use of premarital contraception among sexually active adolescent males and females. All students within the selected classrooms were asked to complete questionnaires assessing attitudes toward contraception, contraceptive knowledge, and sociodemographic and sex-related life history variables. Subjects were rated with regard to their effectiveness of contraception (high, moderate, or low). Separate univariate analyses indicated the following: The low effectiveness group was more likely to perceive responsibility for contraception as belonging to the "opposite gender." Contraception attitudes and knowledge were positively related. Females were more knowledgable about contraception and has more favorable attitudes than males.

Results of previous studies testing the influence of oral contraceptives on relationship satisfaction have produced mixed results. These discrepancies might be explained by the "Congruency hypothesis", which predicts that relationship satisfaction is determined by the congruency (or non-congruency) between current use of oral contraceptives and their use during relationship formation. This is because oral contraceptives appear to alter women's mate preferences, so that attraction to their partner may have changed in non-congruent women. Indeed, previous studies have shown that women in a non-congruent state were less sexually satisfied with their partner, even though they were more generally satisfied in the non- sexual aspects of the relationship. The aim of our study was to test the congruency hypothesis on two groups of couples (couples attending the Center of Assisted Reproduction, and a comparison group of pregnant women and their partners; note that in neither group were women currently using oral contraception). Based on previous studies, we expected that women who used oral contraceptives at the time of relationship formation would report lower sexual satisfaction with their partner than women who were non-users during relationship formation. The study involved a total of 660 couples from...

Métodos: Os totais de 233 e 226 mulheres foram aceitas nos grupos de implantes liberadores de ENG e LNG, respectivamente. Os sinais locais foram avaliados pela inspeção e as mulheres foram questionadas sobre queixas relacionadas ao local do implante aos 14 dias e 3, 6, 12, 24 e 36 meses após a inserção no Brasil e na República Dominicana. O mesmo grupo, somente de mulheres brasileiras, sendo 120 no grupo das usuárias de implantes liberadores de ENG e 127 no grupo liberador de LNG, deu sua opinião com relação à satisfação com o método contraceptivo e com o novo padrão menstrual, através de um questionário desenvolvido para o estudo. Os questionários foram aplicados pessoalmente aos 3 e 6 meses, e em seguida a cada 6 meses, até 36 meses após a inserção. Resultados: Dor e outros sintomas (principalmente prurido) foram as queixas mais frequentemente relatadas (~20%) e foram observadas em uma proporção semelhante entre as usuárias de Implanon® e Jadelle®, e parestesia foi relatada com menos frequência Hiperpigmentação foi três vezes maior entre as usuárias de Jadelle® do que em usuárias de Implanon® (p< 0,0001) e foi mais prevalente entre as usuárias nãobrancas. Todos os sintomas e sinais foram relatados muito mais frequentemente por mulheres dominicanas. Embora todos os sinais locais apresentassem uma tendência a diminuir com o tempo de uso, não houve diferenças significativas quando comparadas as ocorrências aos 12, 24 e 36 meses de uso de ambos os tipos de implantes. No entanto, as usuárias do Jadelle® não apresentaram declínio na ocorrência de hiperpigmentação. O modelo de regressão logística ajustada pela cor e índice de massa corporal (IMC; kg/m2) mostrou que as mulheres brancas usuárias de Implanon® apresentaram risco (OR) menor de hiperpigmentação quando comparadas às usuárias de Jadelle® (OR 0,26; IC 95% 0,14-0,48; OR 0,34; IC 95% 0,14-0,81), respectivamente. Não houve correlação entre dor, parestesia e hiperpigmentação e a utilização dos dois tipos de implantes. Hiperpigmentação foi mais prevalente entre usuárias de Jadelle® de pele escura. Em relação à satisfação foram analisados 1200 questionários. A maioria das usuárias dos dois tipos de implantes estava satisfeita com o método, e a insatisfação foi de aproximadamente 15% ao longo dos 3 anos de observação. Além disso, cerca de 70% das mulheres declararam que a utilização dos implantes trouxe benefícios e só aproximadamente 5% referiram que o uso provocou danos. Com relação ao novo padrão menstrual, as usuárias estavam muito satisfeitas ou satisfeitas em aproximadamente 70%, independente do tipo de implante. A vida sexual das usuárias não apresentou alteração em mais de 70% das usuárias, independentemente do tipo de implante. As usuárias indicariam o método para outra mulher e em sua grande maioria o método foi aprovado pelo marido. Conclusões: Informar as usuárias de implantes sobre sinais e sintomas no local de inserção do implante indica uma boa qualidade de atendimento; no entanto não é necessário avaliar o local de inserção a cada visita em usuárias assintomáticas. Os resultados sobre a opinião das usuárias quanto à satisfação com o método foram similares aos de trabalhos anteriores. No entanto, os resultados devem ser interpretados com cautela porque as mulheres que participaram deste estudo não eram usuárias comuns de uma clínica de planejamento familiar, o que levou a maior orientação durante todo o estudo. Não se pode ignorar a possibilidade de que a alta satisfação seja uma consequência da insatisfação com outros métodos contraceptivos / Abstract: Objectives: The study was conducted to assess the prevalence of local signs and symptoms at the insertion site in the arm, and the evaluation of the women's satisfaction with the method and with the new bleeding patterns among users of subdermal releasing-implants, levonorgestrel (LNG, Jadelle®) and etonogestrel (ENG, Implanon®) systems. Methods: A total of 226 and 233 women were enrolled in the ENG and the LNG group, respectively. Local signs were evaluated and women were questioned regarding complaints related to the insertion site at 14 days and 3, 6, 12, 24, and 36 months after insertion in Brazil and Dominican Republic. The same Brazilian women were randomly enrolled in the satisfaction study of ENG group (120) and the LNG group (127), respectively. The opinion of satisfaction with the bleeding pattern and with the method was evaluated through a questionnaire developed for the study. The questionnaires were applied face- toface at the 3, 6, and every 6 months thereafter up to 36 months after insertion. Results: Pain and other symptoms (mostly pruritus) were the most frequently reported complaints (~20%), and were observed in a similar proportion among both Implanon® and Jadelle® users; paresthesia was less frequently reported. Hyperpigmentation was three fold higher among users of Jadelle® than Implanon® users (p< 0.0001) and was more prevalent among non-white users. All symptoms and signs were reported much more frequently by Dominican women. The logistic regression model adjusted by race and body mass index (BMI; kg/m2) showed that users of Implanon® and white women presented lower risk of hyperpigmentation when compared to Jadelle's users (OR 0.26, 95% CI 0.14-0.48; OR 0.34, 95% CI 0.14-0.81, respectively). There was no relation between pain, paresthesia and hiperpigmentation and the use of the implants. Hiperpigmentation was more prevalent between users of Jadelle® in non-white women. The total number of questionnaires for the satisfaction study was 1,200. The results showed that most of these users of contraceptive implants were satisfied with both implants at the different visits and the regret with the method did not reach ~15% at any time through the 3 years of observation. In addition, almost 70% of the women declared that the use of the implants offered benefits for her and only ~5% referred that the use provoke harm for her. Regarding the women's response to changes in their bleeding patterns following insertion of the implant, the percentage who stated that they were very satisfied or satisfied was 70% in both methods. There was no change in the reported frequency of sexual interc urse during use of the implants and no change in their libido. Moreover, all the women in both groups stated that they would recommend the method to a friend or relative and most of them declared that their partner approved of this contraceptive method. Conclusions: Although information relating to local symptoms and signs at the implant site should be provided to current and potential users as a component of good quality of care, we do not recommend evaluation of the insertion site at every visit in women with no complaints. The results about satisfaction with the method are in agreement with previous findings. However, the results must be interpreted with caution because the women are participating in a research study and were not common clients of a family planning clinic. We cannot ignore the possibility that the high satisfaction was a consequence of dissatisfaction with alternative methods / Doutorado / Tocoginecologia / Doutor em Tocoginecologia

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / A contracepÃÃo de emergÃncia (CE) à um mÃtodo que evita a gravidez apÃs a relaÃÃo sexual. TambÃm conhecido por âpÃlula pÃs-coitoâ, esse mÃtodo utiliza progestogÃnio na forma concentrada e tem indicaÃÃo reservada Ãs situaÃÃes especiais ou de exceÃÃo, tais como falha conhecida ou presumida, uso inadequado e relaÃÃo sexual sem uso de mÃtodo contraceptivo, bem como em casos de violÃncia sexual. Descrever e analisar o nÃvel de conhecimento e a utilizaÃÃo da CE de usuÃrias do ServiÃo de Atendimento FarmacÃutico (SAC FARMA), de uma Rede de FarmÃcias ComunitÃrias em Fortaleza, CearÃ. Entre os meses de outubro de 2008 a maio de 2009, apÃs o esclarecimento de informaÃÃes sobre pÃlula pÃs-coito atravÃs do SAC FARMA, mulheres usuÃrias ou que tinham intenÃÃo de uso da CE, foram convidadas a participar da pesquisa sobre uso de CE. Para tanto, foi aplicado um questionÃrio e os dados foram incluÃdos no programa estatÃstico SPSS, versÃo 15.0. Das 54 entrevistas feitas, a maioria das mulheres estavam entre a faixa etÃria de 23 e 29 anos de idade (44,4%), solteiras (66,7%) e residentes no Estado do Cearà (66,7%). Tinham renda entre 1 e 3 salÃrios mÃnimos (48,1%) e cursavam ensino mÃdio (50,0%) e superior (42,6%). Pretendiam fazer uso ou utilizaram CE sem orientaÃÃo/prescriÃÃo mÃdica (92,6%) e a maioria (54%) obteve alguma informaÃÃo sobre CE atravÃs de amigos e familiares. Mais da metade (64,8%) afirmou que nÃo era a primeira vez de uso, sendo que 82% relataram utilizar uma ou duas vezes. Com relaÃÃo ao conhecimento sobre o risco de diminuiÃÃo de eficÃcia caso houvesse repetiÃÃo do uso, a maioria (64%) relatou desconhecer essa informaÃÃo. Relataram nenhuma reaÃÃo ou queixa (72%) e 98,1% conheciam outro mÃtodo contraceptivo, sendo o preservativo o mais conhecido (92,6%) e utilizado (84%). Um dos principais motivos para justificar a utilizaÃÃo da CE foi o sexo desprotegido (53,7%). Quando perguntadas atà quanto tempo apÃs a relaÃÃo sexual o mÃtodo pode ser utilizado, a maioria respondeu que pode ser atà 72 horas (56,3%), 25% nÃo souberam responder e 65,6% relataram que a âPÃlula do Dia Seguinteâ nÃo possui efeito abortivo. A maioria das mulheres avaliadas pretendia fazer uso ou utilizar a CE sem orientaÃÃo/prescriÃÃo mÃdica, obteve informaÃÃes sobre a pÃlula atravÃs de amigos e familiares e, alÃm disso, nÃo tinha conhecimento sobre o risco de diminuiÃÃo de eficÃcia se o uso for repetitivo. Estes fatos alertam para que se tenha uma maior preocupaÃÃo em relaÃÃo à possibilidade de uso indevido do medicamento e seu fÃcil acesso nas farmÃcias comerciais. / The emergency contraceptive pill (EC) is a method of the emergency contraception that prevents pregnancy after sexual intercourse. It is also known as the âpost coital pillâ and contains high dose progestin-hormone. The EC can be taken immediately or up to five days after sex if the woman did not use birth control, in cases of suspected birth control failure, or if she was forced to have sex. To describe the level of knowledge and use of EC by users of the Medicine Attendance Service (SAC FARMA) in a network of community pharmacies placed in Fortaleza, CearÃ. In the months October (2008) to May (2009), after each enquiry about the âpost coital pillâ, women who were using or intended to use this pill were invited to participate in a survey on the use of emergency contraception by the application of a structured questionnaire. The data were analyzed with the statistical program SPSS, version 15.0. Of the 54 women interviewed, the majority were aged between 23 and 29 years (44.4%), were single (66.7%) and resident in the State of Cearà (66.7%). (48.1%) had income between 1 and 3 minimum wages, 50,0% higher secondary education and 42.6% had higher education.). Almost all (92,6%) wished to use or have used EC without guidance/prescription and of these the majority (54%) obtained some information about EC through friends and family. More than half (64.8%) said it was not their first time of use, and 82% reported using EC once or twice previously. With respect to knowledge about the risk of loss of effectiveness if the use is repetitive, the majority (64%) were unaware of this information. Most (72%) reported no adverse reaction or other complaints. Also, 98.1% of interviewed reported that they knew other method of contraception, being the condom the most widely known (92.6%) and used (84%). One of the main reasons to justify the use of EC was unprotected sex (53.7%). When asked for how long after intercourse the method can be used, most answered within 72 hours (56.3%), 25% did not respond and 65.6% reported that "post coital pill" has no abortive effect. Most of the women studied wanted to use the EC without prescription and obtained information about EC pill from friends and family. Moreover most women had no knowledge about the risk of reduced effectiveness if the use is repetitive. These findings are of concern as they indicate the possibility of misuse of the EC given its easy access in pharmacies.

O argumento central é que não é possível compreender tal escolha sem relacioná-la àquelas dimensões da vida da mulher. A metodologia utilizada foi a observação participante feita nos Grupos de Direitos Reprodutivos realizados nas Unidades Básicas de Saúde da cidade de Juiz de Fora (Minas Gerais), onde há a distribuição gratuita de métodos anticoncepcionais, e entrevistas em profundidade. A observação nos grupos possibilita perceber a existência de dois pontos de vista distintos: o dos profissionais de saúde e o das usuárias. A partir da contraposição entre estes dois pontos de vista, concluímos que estão em jogo, nos grupos, diferentes modos de percepção da Conjugalidade, da Sexualidade e do Corpo, que não são (re)conhecidos pelos profissionais de saúde. / The purpose of this study is to analyze the relationship between the choice of contraceptive method by women who participate in Reproductive Rights Groups and representations of being a woman, their concepts about sexuality and their body. The main argument is that you are unable to understand such a choice without relating it to those dimensions of women's lives. The methodology used was a participant observation of the Groups for Reproductive Rights made in Basic Health Units in Juiz de Fora (Minas Gerais), in which there is free distribution of contraceptives, and in-depth interviews. The groups observation made it possible to identify the existence of two distinct points of view: the health professionals` and the users` ones. From the contrast of these two points, it is concluded that in the groups there are different ways of perception of marital relationship, sexuality and body that are not known (recognized) by health professionals.

Aspectos não completamente elucidados quanto ao momento e tempo de ocorrência podem prejudicar a continuação e ocasionar descontinuação prematura ou induzir morbidades. Objetivos: Avaliar a DMO, ganho do peso e taxas de descontinuação por transtornos de sangramento dos métodos de somente progestágenos. Sujeitos e Métodos: realizaram-se quatro estudos sobre a influência do acetato de medroxiprogesterona de depósito (AMPD): A) sobre a DMO e a composição corporal (CC) de suas usuárias a partir dos 12 meses até os 23 anos de uso; B) sobre ganho de peso em usuárias do AMPD, do sistema liberador de levonorgestrel (SIU-LNG) e do dispositivo intra-uterino com cobre (DIU) até 10 anos de uso, C) sobre a influência do implante liberador de etonogestrel (ENG) na DMO e na CC até 24 meses de seguimento e D) avaliamos a influência de diferentes orientações em relação aos distúrbios do sangramento nas taxas de continuação das usuárias de SIU-LNG, implante liberador de ENG e DIU. Resultados: a DMO aos 12 meses de uso do AMPD foi menor na coluna lombar quando comparadas a usuárias de DIU e aos 10 anos de uso 29,8% das usuárias do AMPD apresentaram osteoporose comparado a 2,4% das usuárias de DIU. Na CC, observou-se que, aos 12 meses, ocorreu um aumento de 2Kg de massa gorda e 2% na porcentagem de massa gorda nas usuárias de AMPD, porém, a longo prazo, não houve diferença na quantidade de massa gorda quando comparadas à usuárias de DIU. O peso aumentou ao final do primeiro ano em 1,3Kg, 0,7Kg e 0,2Kg e, aos 10 anos, em 6,6Kg, 4,0Kg e 4,9Kg nas usuárias de AMPD, SIU-LNG e DIU, respectivamente. Nas usuárias do implante liberador de ENG ocorreu uma diminuição da DMO da coluna lombar aos 12 meses e um aumento de 2% a 2,7% da massa gorda aos 12 e 24 meses comparadas à usuárias de DIU. Mulheres que receberam orientações de rotina ou intensivas quanto ao padrão de sangramento esperado não mostraram diferenças significativas nas taxas de descontinuação do SIU-LNG, do implante liberador de ENG e do DIUT. Conclusões: O uso do AMPD ocasionou uma diminuição na DMO no primeiro ano de uso, essa diminuição foi progressiva e aumentou a prevalência de osteoporose em longo prazo. Usuárias do AMPD, SIU-LNG e DIU apresentaram ganho do peso aos 10 anos de uso, sendo maior em usuárias de AMPD. A massa gorda aumentou no primeiro ano de uso do AMPD, porém, não foi significante em longo prazo quando comparada à usuárias do DIU. Em usuárias do implante liberador de ENG foi encontrado um ganho do peso e da massa gorda aos 24 meses e uma diminuição da DMO após 12 meses. As estratégias de orientação de rotina e intensivas não apresentaram diferenças nas taxas de continuação das usuárias do implante liberador de ENG , SIU-LNG e DIU / Abstract: The decrease in bone mineral density (BMD), weight gain and changes in uterine bleeding patterns are often associated with the use of progestin-only methods. Aspects not still elucidated and the moment of occurrence could harm the continuation and provoke premature discontinuation or induce morbidities. Objectives: To evaluate BMD, weight gain and discontinuation rates for bleeding disturbances of progestin-only methods. Subjects and Methods: Four studies were conducted with depot medroxyprogesterone acetate (DMPA) users: A) regarding BMD and body composition (BC) from 12 months to 23 years of use; B) on weight gain among DMPA users, the levonorgestrel-releasing intrauterine system (LNG-IUS) and cooper-intrauterine device (IUD) up to 10 years of use; C) on the influence of the etonogestrel-releasing implant (ENG) upon BMD and BC up to 24 months of follow-up; and D) to evaluate the influence of two counseling strategies regarding to bleeding disorders in continuation rates of the users of the LNG-IUS, ENG-implant and IUD. Results: BMD after 12 months of DMPA use was lower at the lumbar spine compared to IUD users and 29.8% has osteoporosis among those women who had used DMPA for 10 years or more compared to 2.4% of IUD users. Regarding BC, at 12 months of use it was observed, an increase of 2 kg of fat mass and 2% in the percentage of fat mass in DMPA users; however, in the long-term use, there was no difference in the amount of fat mass compared to IUD users. The weight increased at the end of the first year was 1.3kg, 0.7kg and 0.2kg and, at 10 years, was 6.6kg, 4.0kg and 4.9kg among DMPA-, LNG-IUS- and IUD-users, respectively. Users of the ENG-implant showed a decrease in BMD at lumbar spine after 12 months of use and an increase of 2% to 2.7% of fat mass at 12 and 24 months when compared to IUD-users. Women who received routine or "intensive" counseling about the expected bleeding patterns showed no significant differences regarding the rates of discontinuation of LNG-IUS, ENG-implant and IUD. Conclusions: Users of DMPA showed a decrease in BMD at the end of the first year of use, the decrease was progressive and an increased prevalence of osteoporosis in the long-term use was observed. DMPA, LNG-IUS and IUD users showed weight gain after 10 years of use, higher in DMPA users. Fat mass increased in the first year of DMPA use; however, was not significant in the long-term when compared to IUD-users. In ENG-implant users it was found a weight gain and increase of fat mass at 24 months and a reduction in BMD after 12 months of use. The routine and "intensive" counseling showed no differences in rates of continuation in ENG-implant, LNG-IUS- and IUD-users / Doutorado / Fisiopatologia Ginecológica / Doutora em Ciências da Saúde

Objetivo: Caracterizar o conhecimento e uso de métodos anticoncepcionais entre adolescentes de escolas públicas. Métodos: Estudo transversal, realizado com amostra probabilística e representativa de 363 adolescentes, de ambos os sexos, que não viviam conjugalmente, com idades entre 13 e 17 anos, matriculados no período diurno, de escolas públicas, da zona urbana do município de Cruzeiro do Sul, Estado do Acre, em 2008. A pesquisa contemplou as exigências éticas. A caracterização de conhecimento e uso de métodos anticoncepcionais foi feita, a partir da aplicação de um questionário estruturado, contendo perguntas fechadas e abertas sobre sexualidade e métodos contraceptivos. Dados coletados foram digitados, revisados e processados. O banco de dados foi constituído e analisado, estatisticamente, com a utilização do software Epi Info (version 3.5.8; 2008). Os dados foram descritos, utilizando a estatística descritiva: distribuição de freqüência, medidas de tendência central e medida de dispersão. Para identificação de diferenças entre grupos de adolescentes foi utilizado o teste Quiquadrado de Pearson ou Exato de Fisher. Resultados: Dos 363 adolescentes, 55,4por cento eram do sexo feminino e 44,6por cento, do masculino, com média de idade de 14,7 (dp=1,3) anos; 32,0por cento afirmaram que haviam iniciado a vida sexual, as moças, com média de idade de 15,0 (dp=1,3) anos e os rapazes, com 13,3 (dp=1,3) anos; 98,9por cento referiram conhecer algum tipo de MAC, especialmente, o preservativo (95,3por cento) e a pílula (80,1por cento). Mais do que metade das moças e rapazes, respectivamente, 58,3por cento e 59,6por cento, referiram conhecer entre 1 e 4 tipos de MAC. Dentre os que iniciaram, ou não, a vida sexual, 78,4por cento e 65,6por cento, respectivamente, já tinham ouvido falar sobre dupla proteção. Dentre aqueles com vida sexual ativa, 79,3por cento das moças e 81,0por cento dos rapazes referiram terem feito uso de preservativo na primeira e na última relação sexual. Igualmente, 87,5por cento das garotas e 72,1por cento dos garotos, referiram fazer uso de camisinha em todas as relações sexuais. Conclusão: O alto nível de conhecimento de MAC e o elevado uso de preservativo sexual masculino entre esses adolescentes podem expressar resultados positivos das políticas públicas de saúde sexual e reprodutiva atuais, contribuindo para diminuição de gravidez não planejada e de infecções por doenças transmitidas por via sexual / To characterize the knowledge and use of contraceptive methods among public school students. Methods: Transversal study, accomplished with probabilistic and representative sample of 363 adolescents, man and woman, who didnt live conjugally, between 13 and 17 years old, matriculated in diurnal period, in public schools, in the urban area of Cruzeiro do Sul District, Acre State, in 2008. The research observed the ethic requirements. The characterization of the knowledge and use of contraceptive methods was done with the application of a structured questionary, containing open and closed questions about sexuality and contraceptive methods. The gathered data were digitated, revised and processed. The data bank was constituded and analyzed, statistically, using the software Epi Info (version 3.5:8; 2008). The data were described, using the descriptive statistic: frequency distribution, central trend measures and dispersion measure. For the identification of the differences among the adolescent groups it was used the Qui-square test of Pearson or Exact of Fisher. Results: From the 363 adolescents, 55,4per cent were female and 44,6per cent male, with average age of 14,7 (dp=1,3) years old; 32,0per cent told that they had begun sexual life, the girls with average age of 15,0 (dp=1,3) years old and the boys, with 13,3 (dp=1,3) years old; 98,9per cent affirmed to know some kind of MAC, especially the preservative (95,3per cent) and the contraceptive pills (80,1per cent). More than half of the girls and boys, respectively, 58,3per cent and 59,6per cent affirmed to know between 1 and 4 kinds of MAC. Among the ones who had begun, or not, sexual life, 78,4per cent and 65,6per cent, respectively, had already heard about double protection. Among the ones with active sexual life, 79,3per cent of the girls and 81,0per cent of the boys affirmed that they had already made use of preservative during the first and the last intercourse. Identically, 87,5per cent of the girls and 72,1per cent of the boys affirmed that they use condom in every intercourse. Conclusions: The high level of knowledge of MAC and the high use of male sexual preservative among those adolescents can express positive results of the current public sexual and reproductive health policies, contributing with the decrease of the non-planned pregnancy and infections by sexually transmitted diseases

Philosophiae Doctor - PhD / The first objective of this study is to show if diffusion of contraception in areas of traditional high fertility has gone through profound changes. Indeed, we would like to know if contraceptive behaviours have evolved because of new fertility perceptions and also because partners now have greater freedom to make choices in a relationship. The second objective of this study is not only to highlight the levels and trends of contraception and the factors influencing their use (government policies, role of family planning, etc.) in developing countries, but also to consider the population of unmet-needs of contraception. Indeed, the level of contraceptive use depends obviously on users, but also on non-users with no needs and non-users with unsatisfied needs. The understanding of this last category of females is essential to a more accurate estimation of contraception levels, and, therefore for the estimation of fertility levels. This study analyses the contraceptive use in several developing countries in Africa and highlights the unsatisfied needs of contraception, to understand why such needs exist. To do so, we shall analyse available demographic data for thirty-five African countries by using the available Demographic and Health Surveys (DHS), from the 1980's to 2000's considering the DHS I, DHS II, DHS III and DHS IV. This great variety of surveys, seventy-nine in total, permits one to compare levels of contraception and 'unmet-needs' from country to country. The surveys also, make it possible to compare the evolution over time of specific countries or specific regions, and to subsequently comprehend the determining factors of contraceptive use or non-use. / South Africa
