Introdução A obesidade entre adolescentes é um problema que afeta a saúde pública como um todo. Pode ser caracterizada como um distúrbio do estado nutricional normal que gera um aumento de tecido adiposo, reflexo do excesso de gordura resultante do balanço energético positivo. É uma doença multifatorial de origem desconhecida com diagnóstico complexo. As ações de saúde direcionadas para os jovens com essa patologia, devem levar em consideração importantes aspectos dessa fase da vida do indivíduo. A transição da infância para a vida adulta acarreta mudanças biológicas, cognitivas, emocionais e sociais para os adolescentes. Objetivo - Compreender um dos problemas relacionados ao corpo na contemporaneidade na visão de adolescentes em estão em tratamento; o significado de emagrecer e possuir um corpo magro para as mesmas. Métodos - Pesquisa exploratória de corte qualitativo que busca as representações sociais das adolescentes que fazem parte do Programa de Atividades ao Paciente Obeso (PAPO); um programa multidisciplinar que visa a mudança de comportamento para melhora na qualidade de vida e conseqüente perda de peso. A análise foi feita com base na metodologia do Discurso do Sujeito Coletivo. Podendo assim resgatar as representações sociais presentes nas falas das adolescentes acerca do tema. Resultados - As adolescentes quase na sua totalidade apontam que alimentação errada/ maus hábitos em casa e emoções negativas levam a compulsão por comida, sendo fatores determinantes para o acúmulo de peso.

Several studies have documented a deficiency in the delivery of preventive services to adolescents during physician visits in the United States. In many instances, a correlation has been noted between insufficient training and provision of adolescent medicine services in the practicing physician population. The American Medical Association, American Academy of Pediatrics, American Academy of Family Physicians, American College of Obstetrics and Gynecology and Society for Adolescent Medicine recommend adolescent providers deliver comprehensive health services to teenagers. This study sought to assess and compare Pediatric, Family Medicine and Obstetric-Gynecology resident perceptions of their responsibility, training, experience and comfort with providing comprehensive health care services adolescents. We asked residents to identify the following: (1) adolescent health services they considered part of their scope of practice in their respective field; (2) the level of training they had received with regard to select adolescent health services; (3) the experience they had performing select clinical activities with adolescents; and (4) their comfort with aspects of adolescent care. We further asked two questions to test resident knowledge of an adolescents right to consent to contraception or an abortion without parental notification in the state of their residency. A total of 87 residents (31 Obstetric-Gynecology, 29 Family Medicine and 27 Pediatric) were surveyed. Most residents from all three fields felt the full range of adolescent preventive and clinical services represented in the survey fell under the scope of their practice. Most residents also reported high levels of comfort with examined aspects of adolescent care. In regard to some activities, the positive scope and comfort responses were matched by high reported levels of training and experience, including defining confidentiality; counseling about eating, exercise and obesity; counseling about substance abuse; and discussing STDs, sexual partners and contraception. However, for multiple key adolescent services, considerable discrepancies existed between reported levels of training and experience and the positive responses concerning scope and comfort. In particular the results of study suggested all residents need considerably more training and experience with mental health issues, referring teenagers for substance abuse treatment, and addressing physical and sexual abuse. Overall, there were also significant differences between fields. Family Medicine residents reported the greatest potential for providing comprehensive health care. However, they suffered from the overall deficiencies in training and experience noted above. Obstetric-Gynecology residents reported deficiencies in the provision of several preventive counseling and general health services. Pediatric residents reported multiple deficiencies in the provision of sexual health services. Our results indicate, at this time and in the near future, it is unlikely that adolescents will be able to obtain the full range of recommended preventive and clinical services in a single physician visit unless residencies programs actively incorporate increased training in the full range of adolescent preventive and clinical health services.

Despite older adolescence being a risk period for the development of mental health concerns, mental health service engagement is low amongst 16-18 year olds. As therapeutic attendance is linked to clinical outcome, it is important to understand engagement in this population. There is a paucity of research looking specifically at the older adolescent engagement phenomenon. Previous qualitative research into adolescent experiences has provided rich and detailed results. Ten 16-18 years olds, engaged in Child and Adolescent Mental Health Services, were recruited from two London-based services. Each young person was interviewed in order to understand their personal experience of engaging in mental health services. Interviews were transcribed and underwent Interpretative Phenomenological Analysis. Analysis produced twelve subthemes subsumed within five superordinate themes: engagement begins at help seeking, strength of inner resolve, evolution of the self, in the clinic room, and, existing within service walls: physical and policy-based boundaries. Themes are discussed in detail. Conclusions are drawn in relation to previous theory and research. When considering 16-18 year understandings of the engagement phenomena, key elements include: clinician and service developmental appropriateness, negotiation of developmental tasks in relation to engagement, experience of the physical building environment, and awareness of service policy limitations. Suggestions for clinical practice in relation to engagement facilitators and threat are made, and recommendations for future research proposed.

Positive health-related behaviour is particularly important for liver transplant recipients’ (LTRs) recovery. However, non-adherence in adolescents post-transplant is thought to be greater than, or equal to, 50%. Literature searches have found limited research into the area of young adults’ experiences of having a donated liver. Knowing more of their experience seems important to help inform practice to improve adherence and ultimately save lives. The present study aimed to construct a grounded theory of young adults’ experiences of having a liver transplant, in order to better understand how young adults may adjust following such experiences. Semi-structured interviews were conducted with twelve liver transplant recipients (LTRs; five female, seven male). Data were analysed using constructivist grounded theory. A model was constructed to capture the dynamic interactions between thirteen categories, resulting in four main themes: Finding Identity Post-Transplant, Carrying Responsibility, Unseen, Unspoken or Misunderstood Challenges and Adjusting to Life After Transplant. The study highlights the importance of the themes in psychological adjustment post-transplant. Understanding this process is imperative in order to improve health-related behaviours in a cohort with traditionally poor adherence. Implications for further research and clinical practice are discussed, including educating LTRs to raise their levels of self-efficacy, which have a positive impact on adherence.

Objetivo: Avaliar a eficácia de sessões de aconselhamento em amamentação dirigidas a mães adolescentes e avós maternas sobre o uso desnecessário de água e/ou chás em crianças amamentadas. Métodos: Foi conduzido um ensaio clínico randomizado envolvendo 323 mães adolescentes, seus recém-nascidos e as avós maternas das crianças, alocadas para quatro grupos distintos: mãe e avó não coabitando, sem intervenção e com intervenção direcionada apenas à mãe; e mãe e avó coabitando, sem intervenção e com intervenção direcionada a ambas. A intervenção consistiu de seis sessões de aconselhamento em amamentação, na maternidade e aos sete, 15, 30, 60 e 120 dias. As informações sobre as práticas alimentares das crianças foram coletadas mensalmente nos primeiros 6 meses de idade por telefone. O impacto da intervenção foi medido, comparando-se as medianas e as curvas de sobrevida da introdução desses líquidos e a regressão de Cox estimou a sua magnitude. Resultados: A intervenção teve impacto positivo significativo tanto para o grupo em que apenas as mães adolescentes a receberam (RDI=0,48; IC95%=0,31-0,76) quanto para o grupo em que as avós foram incluídas (RDI=0,53; IC95=0,35-0,80). Ela postergou em 44 dias o uso desses líquidos no primeiro grupo (78 dias versus 122 dias) e em 67 dias no grupo em que as avós foram incluídas na intervenção (63 dias versus 130 dias). Conclusões: Múltiplas sessões de aconselhamento nos primeiros 4 meses dirigidas a mães adolescentes e avós maternas, quando estas coabitavam, mostraram ser uma estratégia eficaz em postergar a introdução desnecessária de água e/ou chás em crianças amamentadas. / Objective: To evaluate the efficacy of counselling sessions on breastfeeding for adolescent mothers and maternal grandmothers on the reduction of unnecessary water and/ or herbal teas intake on breastfed infants. Methods: A randomized clinical trial was conducted involving 323 adolescent mothers, their newborn infants and respective maternal grandmothers allocated into four distinct groups: mother and grandmother not cohabitating, without or with intervention directed only towards mother; and mother and grandmother cohabitating without or with intervention directed towards both (mother and grandmother). The intervention consisted of six counselling sessions on breastfeeding, in the maternity ward and on days 7, 15, 30, 60 and 120 after birth. The data about feeding practices were collected monthly until the end of the sixth month of life by telephone. The impact of the intervention was measured by comparing the medians and the survival curves for initiation of water/tea intake in the first six months of life between the groups and Cox regression was used to estimate its magnitude. Results: The intervention had a significant positive impact for both the group in which only adolescent mothers received the intervention (HR=0,48; 95%CI=0,31-0,76) and for the group in which grandmothers were also included (HR=0,53; 95%CI=0,35-0,80). It postponed in 44 days the use of these liquids on first group (78 days versus 122 days) and in 67 days on the group in which the grandmother was also included in the intervention (63 days versus 130 days). Conclusions: Multiple counselling sessions on infant feeding in the first 4 months postpartum for adolescent mothers and maternal grandmothers, when they cohabitate, demonstrated to be an effective strategy to postpone the unnecessary water and/or teas intake on breastfed infants.

Helsestasjon for ungdom er et av flere tiltak innenfor det lokale folkehelsearbeidet hvor det gis enmulighet til å styrke unges mestringsevne og helseatferd i ungdomstiden og senere i voksen alder.Ungdom er framtidens brukere av den generelle helsetjenesten. De erfaringer unge gjør i sine første møter med helsepersonell vil ha betydning for deres nåværende og senere bruk av helsetjenesten. Hensikten med denne studien var å få en bedre forståelse og innsikt i hva ungdom opplever i møtet og relasjonen med helsepersonell og helsestasjonen som system. Undersøkelsen gikk ut på å finne ut hvilke forventninger, erfaringer og opplevelser ungdom hadde til helsestasjonen i forhold til sine helsebehov. Datamaterialet er basert på intervju med ni ungdommer av begge kjønn i aldersgruppen 16-20 år rekruttert fra forskjellige helsestasjoner i Nordland og Troms fylke. Intervjuene i studien varsemistrukturerte slik at informantene hadde muligheter til å fortelle beretninger. Metoden Grounded Theory ble brukt som analytisk tilnærming. Resultatet av studien viste at unge opplever en umiddelbar tillit til personell og institusjonen helsestasjon for ungdom. Når så ungdom møtte helsepersonell med gode kommunikasjonsferdighetersom ivaretok deres behov for konfidensialitet og hadde tro på at unge er i stand til å gjøre gode helsevalg for seg selv, ga dette en sirkeleffektmed en fornyet eller bekreftet tillit til personell og institusjon. Tillit ble det sentrale analytiske fokuset i denne studien. Tillit er en forutsetning for å skape gode prosesser, der ungdom ikke bare ender opp med en mer tillitsfull relasjon tilhelsevesenet, men også med en større tillit til egneholdninger og vurderinger. Tillit inngår således som et sentralt element i en empowerment prosess hvor resultatet etter gode møter kunne blimestring og økt selvfølelse og selvtillit. I motsatt fall ble møter disempowering og førte til tillitssvekkelse og redusert bruk av helsetjenesten. Studien peker også på fenomenet tillitssmitte,hvor den enkelte ungdom bringer med seg erfaringer fra helsestasjonen ut i vennekretsen ogungdomsmiljøet. Ungdom overtar den enes erfaring som igjen blir til den andres forventning. Helsepersonell bør tilbysrelevante etterutdanningsprogram for å sikre en kunnskapsbasert praksis hvor noe av innholdet i slike etterutdanningsprogram bør være å øke kompetansen omkommunikasjonens betydning i møtet med ungdom. Det gjelder for fagpersonell å forstå tillitens ”natur”, hvordan den oppstår, vedlikeholdes, og hvor sårbar den kan være. Uten at denne grunnleggende tillit er til stede, vil en vanskelig kunne lykkes i folkehelsearbeidet. / Health clinics for adolescents are one of several services within the local public health. Such clinics may help adolescent to achieve control over the factors which affect their lives and their healthbehavior now and in the future. Adolescents are the next generation users of the general healthservices. The first experiences in their interactions with health professionals are of significanceregarding later use of health services. The purpose of this study was to increase our understanding of the relations between adolescents, health personnel and the health clinic as a system. The study tried to find out adolescentsexpectations, experiences and perception when theyattended the service. Data was collected from youth of both sexes between 16-20 years who called on adolescent health clinics in two counties in northern Norway. The interviews were semi-structured giving the informants the possibility to do narratives. The interviews were analyzed in the tradition of grounded theory. The results of the study showed that adolescents perceived spontaneous trust in the health clinics andhealth professionals. Effective communication skills, assuring confidentiality and confidence in the youth’s ability to make good decisions regarding their own health, generated renewed trust inprofessionals and the institution. Trust became the analytic focus in this study. Trust is a key elementin the empowerment process which may result in adolescents increased control and self-confidence.If not, it may have dis-empowering effects and thus lead to reduced trust and less use of health services. The study also points out the phenomena of trust as “catching”, as one adolescent brings hisand hers experiences to their group of friends. In this way, the perceptions of trust/mistrust fluctuatebetween and among the youth; one persons experience will be another’s expectation. Health professionals should be given access to relevant postgraduate courses in order to secureevidence based practice where the content of education should increase their attention aboutcommunication when they meet with young people in health services. Professionals have to understand the nature of trust, how it is generated, maintained and how easily it can be diminished. Without trust present, the public health work will suffer. / <p>ISBN 91-7997-098-2</p>
