Common Mental Disorder and early interruption of exclusive maternal breastfeeding in Quilombola women: a population-based study / Transtorno mental comum e interrupção precoce do aleitamento materno exclusivo em mulheres quilombolas: estudo de base populacional

Abstract Objectives: to investigate the prevalence of exclusive maternal breastfeeding (EMBF) and evaluate whether common mental disorder (CMD) and other predictors promote its early interruption (EI-EMBF4). Methods: a cross-sectional study involving all children <24 months (n=252) residing in 50% (n=34) of the Quilombola communities in Alagoas. The EI-EMBF4 was established when EMBF was ≤4 months. The Self-Reporting Questionnaire was used to identify the occurrence of CMD. Other predictors were obtained through interviews. The measure of association was the prevalence ratio calculated by the Poisson regression, following a hierarchical theoretical model. The prevalence of EMBF for 4 and 6 months, and its median duration (survival analysis) were calculated. Results: the prevalence of EI-EMBF4 and CMD was 57.6% and 42.9%, respectively. The risk factors independently associated with EI-EMBF4 were: living in a mud house, maternal age ≤18 years, low birth weight and the use of a pacifier or baby bottle. There was no association with CMD. The prevalence of EMBF for four and six months was 42.4% and 25.4%, respectively, and the median duration was 106 days. Conclusion: EMBF indicators are below the established recommendations, justifying the implementation of measures that prioritize women subjected to risk factors identified here. CMD is not configured among these.

Resumo Objetivos: investigar a prevalência do aleitamento materno exclusivo (AME) e se o transtorno mental comum (TMC) e outros preditores promovem sua interrupção precoce (IP- AME4). Métodos: estudo transversal envolvendo todas as crianças <24 meses (n=252) residentes em 50% (n=34) das comunidades quilombolas de Alagoas. A IP-AME4 foi definida quando o AME foi ≤ 4 meses. Utilizou-se o Self-Reporting Questionnaire para identificar o TMC. Outros preditores foram obtidos por meio de entrevista. A medida de associação foi a razão de prevalência calculada por regressão de Poisson, seguindo modelo teórico hierárquico. Foram calculadas as prevalências de AME por 4 e 6 meses e sua duração mediana (análise de sobrevivência). Resultados: as prevalências de IP-AME4 e do TMC foram 57,6% e 42,9%, respectivamente. Os fatores de risco independentemente associados à IP-AME4 foram: residir em casa de taipa, idade materna ≤18 anos, baixo peso ao nascer e uso de chupeta ou de mamadeira. Não houve associação com TMC. As prevalências do AME por quatro e por seis meses foram 42,4% e 25,4%, nessa ordem, e a duração mediana foi de 106 dias. Conclusão: os indicadores de AME estão aquém das metas estabelecidas, justificando a implementação de medidas que atuem sobre os fatores de risco aqui identificados, sendo que o TMC não se configura entre esses.

Stunting and overweight among children in Northeast Brazil: prevalence, trends (1992-2005-2015) and associated risk factors from repeated cross-sectional surveys.

BACKGROUND: A study involving children from Alagoas (Northeast Brazil) revealed that, as a consequence of a drastic reduction in the prevalence of stunting between 1992 to 2005, (22.5 to 11.4%) combined with an increase in overweight prevalence (6.7 to 9.3%), the prevalence of these two conditions in 2005 was very close. If these trends were maintained, it is very likely that, at this time, the childhood overweight prevalence has already exceeded that of the stunting. However, no study is available to confirm this hypothesis. The identification of these changes is relevant to the planning and evaluation of public policies. This study aimed to investigate the prevalence, time trends and associated factors with stunting and overweight in children from Alagoas. METHODS: Independent cross-sectional household surveys were conducted in 1992 (n = 1231), 2005 (n = 1381) and 2015 (n = 988). Data were collected from probabilistic samples of children aged 0-60 months. Stunting was defined by stature-for-age < - 2 sd and overweight by weight-for-stature > 2 sd. RESULTS: Between 1992, 2005 and 2015, the stunting prevalence was 22.6, 11.2 and 3.2% (reduction of 85.8%), while the overweight prevalence was 6.9, 7.5 and 14.9% (increase of 115.9%), respectively. After multivariate analysis, the following positive associations with stunting were observed in 1992: age group > 24 months (28.3% vs 14.5%), mother with ≥2 children (28.8% vs 12.8%), low birth weight (28.3% vs 15.7%) and mother with low schooling (29.3% vs 7.2%). In 2015 there was a higher prevalence of stunting in males (4.2% vs 2.2%), in children < 24 months (4.6% vs 2.2%), with low birth weight (8.6% vs 3.0%) and in those who had mothers with low schooling (7.0% vs 2.6%). Regarding overweight, in 1992 there was higher prevalence for male (9.1% vs 4.7%) and in children whose mothers had ≤2 children (8.9% vs 5.8%), while in 2015 only birth weight >  4 kg was associated to overweight (27.3% vs 14.2%). CONCLUSIONS: During the analyzed period, there was a significant decrease in stunting prevalence. At the same time, a substantial increase was observed in the overweight prevalence. Currently, stunting is a problem of low magnitude, while overweight has become a worrying public health problem.
