Although there is a growing body of research in the area of adolescent pregnancy and parenting, relatively little research has addressed the psychological effects of pregnancy on the adolescent. A descriptive correlational study was utilized to examine levels of depressive symptomatology, self-esteem, perceived social support from family and friends, and the relationship among these variables in the pregnant adolescent. A second purpose of the study was to describe characteristics of the pregnant adolescent (age, race or ethnicity and educational level). The theoretical framework for this study was derived from The Conceptual Model of Support During Adolescent Pregnancy. Participants for the study were recruited from two school programs for pregnant adolescents, a physicians office, and a clinic. A convenience sample of 90 single pregnant teens between the ages of 13 to 18 participated in the study. The teens completed a demographic form and four questionnaires: the Reynolds Adolescent Depression Scale, the Rosenberg Self-Esteem Scale, the Perceived Social Support from Family Scale, and the Perceived Social Support from Friends Scale. Demographic data were analyzed using descriptive statistics. A one-way analysis of variance (ANOVA) was computed to determine the significance between the depression scores and each of the demographic variables. The relationship between the adolescent's total depression score and self-esteem, perceived family support, and perceived peer support were determined by computing Pearson product-moment correlations. Regression analyses were conducted to determine the best linear model to explain the variance in the total depression scores and the combination of the independent variables (self-esteem, perceived social support from family, and perceived social support from friends) in the pregnant adolescent. Thirteen (14%) of the adolescents exceeded the cutoff score of 77. The regression analysis of the RADS-2 score on the predictor variables (self-esteem, perceived support from family, and perceived support from friends) accounts for 56.9% of variance in depression of adolescents during pregnancy. The adolescents in this study who experienced increased self-esteem and perceived support from family and friends had decreased scores on the RADS-2 scale. Increased self-esteem or feelings of self-worth was the most significant variable in this study as a predictor of depressive symptomatology.

Studies show there is in human milk protective antibodies against intestinal parasites and a relationship between the absence of breastfeeding or weaning and parasitic infections. This work was a prospective cohort study involving 34 pregnant adolescents attended school in Maternity Januario Cicco / RN and their children, to assess the influence of breastfeeding on intestinal parasites in them. Thus, the parasitic infection was investigated by examination of feces parasitological and environmental factors by use of questionnaires. The average age of the mothers studied was 16.2 years. Of these 76.4% were infected and the most prevalent species of parasites were Entamoeba histolytica/dispar (76.9%), Giardia lamblia (19.2%) and Ascaris lumbricoides (11.5%). The infected children had an average age of 5.1 months and the frequency of parasites was 61.7%. The infection was earlier detecctada with 45 days of life. The most common parasites were Giardia lamblia (40%), Entamoeba histolytica/dispar (35%), Ascaris lumbricoides (5%) and Ancylostoma (5%). The average length of exclusive breastfeeding was 2.2 months. There was an association between increased duration of exclusive breastfeeding and increased time to detection of parasites in the feces of children. There was no statistically significant correlation between the socio-economic conditions and cultural and breastfeeding. The data reinforce the importance of breastfeeding to protect the children in its first year of life / A amamenta??o exclusiva nos primeiros seis meses de vida constitui pr?tica indispens?vel para a sa?de e o desenvolvimento da crian?a. Estudos mostram existir no leite humano anticorpos protetores contra enteroparasitos e uma rela??o entre a aus?ncia do aleitamento ou desmame e infec??es parasit?rias. Neste trabalho realizou-se um estudo de coorte prospectivo, envolvendo 34 gestantes adolescentes atendidas na Maternidade Escola Janu?rio Cicco/RN e seus filhos, para avaliar a influ?ncia do aleitamento materno nas parasitoses intestinais dos mesmos. Para tanto, a infec??o parasit?ria foi investigada por exame parasitol?gico de fezes e os fatores ambientais por aplica??o de question?rios. A idade m?dia das m?es estudadas variou de 14 a 19 anos, com m?dia de 16,2 anos. Destas, 76,4% estavam infectadas e as esp?cies de parasitos mais prevalentes foram Entamoeba histolytica/dispar (76,9%), Giardia lamblia (19,2%) e Ascaris lumbricoides (11,5%). Os filhos infectados apresentaram m?dia de idade de 5,1 meses e a frequ?ncia de parasitoses foi de 61,7%. A infec??o mais precoce foi detecctada com 45 dias de vida. Os parasitas mais freq?entes foram: Giardia lamblia (40%), Entamoeba histolytica/dispar (35%), Ascaris lumbricoides (5%) e Ancylostomo (5%). O tempo m?dio de amamenta??o exclusiva foi de 2,2 meses. Observou-se associa??o entre um maior tempo de amamenta??o exclusiva e um maior tempo para a detec??o de parasitos nas fezes das crian?as. N?o foi encontrada correla??o estatisticamente significativa entre as condi??es socioecon?micas e culturais e a amamenta??o. Os dados obtidos refor?am a grande import?ncia do aleitamento materno em proteger a crian?a no seu primeiro ano de vida

No. of bitstreams: 0 Previous issue date: 2009 / O presente estudo teve como principal propósito analisar o estado nutricional de gestantes adolescentes do Município do Rio de Janeiro, identificando características maternas associadas ao desfecho obstétrico peso ao nascer e validando um método para o diagnósticode ganho de peso gestacional. O desenho do estudo foi descritivo do tipo transversal desenvolvido com dados primários obtidos com o Estudo da Morbi-mortalidade e da Atenção Peri e Neonatal no MRJ, 1999-2001. A análise estatística foi dirigida a testar a hipótese de homogeneidade de proporções mediante análises bi e multivariada, com o uso de regressão logística multivariada e sua apresentação dividi-se em três artigos. O primeiro é uma revisão sistemática que visou a identificação de métodos de avaliação nutricional de gestantes adotados no Brasil e sua associação com desfechos obstétricos. / The main purpose of the current study is to analyze the nutritional state of pregnant adolescents in Rio de Janeiro, identifying maternal characteristics associated with the outcome of obstetric birth weight and validating a method for diagnosis of gestational weight gain. The design of the study was descriptive and cross sectional with the primary data obtained from “Study of Morbidity/Mortality and Care in Neonatal and Perinatal in the Municipal of Rio de Janeiro, 1999-2001.” Statistical analysis was aimed at testing the hypothesis of homogeneity of mean ratio by bi- and multivariate analysis – using multivariate logistic regression and its results are presented in this series of three articles. The first is a systematic review aimed at identification of methods of nutritional evaluation of pregnant women utilized in Brazil and its association with obstetric outcomes. There were 26 studies identified using the method recommended by Rosso(1985),the results demonstrate a serious discrepancy of literature, in quantity and quality, that contributes to evaluating the effectiveness of methods of anthropometric assessment of pregnant Brazilian women. The development of studies with methodological rigor in this area is needed and must address age differences as well as biological, socioeconomic and environmental factors of pregnant women. The second article aims to verify the association of maternal characteristics and the obstetric results of gestational weight gain among adolescent mothers in Rio de Janeiro. Included is a subsample of 703 adolescent mothers that carried full term. The results showed an association between the number of prenatal visits and weight gain during pregnancy, as well as an increase in the proportion of excessive weight gain amongst pregnant adolescents, particularly in the youngest adolescents. It concluded that the pre-natal consults improve quantity of weight gain but did not guarantee the quality of this gain, in particular for the younger adolescents. The quality of weight gain could have improved if pre natal nutritional care was valued and the recommendations utilized were geared torwards the specific nutritional standards for adolescents, from the beginning of the pregnancy. The third article assesses the performance of different methods of anthropometric evaluation of pregnant adolescents in predicting birth weight. The study was conducted with a subsample of 826 adolescent mothers. The evaluation of weight gain at the end of their pregnancy was assessed by following the recommendated method of the Institute of Medicine (IOM,1990;92), and adaptations of the MS (2006) following the recommended classification of pre-gestational BMI for adolescents (WHO,1995;2007) Low birth weight was defined as “less than 2500 grams” (WHO, 1995) for children born full term, “below the 10th percentile” for those born at less than 37 weeks of gestation, and a macrosomia as weight equal to or greater than 4000 grams. For small maternal stature a cutoff was used of falling below the 3rd percentile (WHO, 2007). Calculation of SE, E, VPP, VPN and the accuracy of the evaluation of gestational weight gain for the prediction of the BW. Given the growing epidemic of obesity in increasingly early age, the best option for assessment is the anthropometric pre-gestational nutritional method as recommended by WHO (2007), specifically for adolescents. This ensures a prediction of gestational weight gain within the internationally recommended ranges (IOM, 1990;92) and contributes to favorable outcomes, improving future prospects for the mother and child.
