Fatores associados à retenção de peso pós-parto em uma coorte de mulheres, 2005-2007

Post-partum weight retention in Northeastern Brazilian women: a prospective NISAMI cohort study

BACKGROUND

Weight retention during the post-partum period is associated with excessive weight gain.

OBJECTIVES

To investigate factors associated with maternal weight retention at six months post-partum (PPWR).

DESIGN AND SETTING

A prospective cohort study was conducted with 127 women monitored using prenatal services.

METHODS

The outcome variable was represented by post-partum maternal weight retention and calculated as the difference between the mother's weight at sixth month post-partum and her pregestational weight.

RESULTS

The mean age of the pregnant women was 26.7 ± 5.25 years old, and the post-partum maternal weight retention was 46.5%. The proximal determinants showed a direct association with PPWR after adjusting for the distal and intermediate variables: excessive gestational weight gain (odds ratio [OR]:3.34; confidence interval [CI]:1.16-9.59), greater adhesion to dietary intake pattern 2 (composed of red meats and derivatives, eggs, industrialized foods, and coffee) (OR:2.70; CI:1.16-6.32), and the absence of exclusive maternal breastfeeding in the first month (OR:3.40; CI:1.27-9.12), as well as primiparity (OR:2.36; CI:1.00-5.55), an intermediate determinant. Insufficient weight gain in pregnancy was inversely associated with the outcome (OR:0.35; CI:0.31-0.93).

CONCLUSIONS

Among the hierarchical determinants, proximal factors were interrelated with maternal weight retention, indicating that excessive total weight gain, an inadequate dietary intake pattern, and the absence of exclusive maternal breastfeeding in the first month of life work as dampeners of the return to pre-gestational weight. Prepartum and post-partum care interventions can contribute to reducing excess weight in women.

Longer duration of exclusive breastfeeding reduces maternal weight retention: results from the CLaB study

Abstract Objectives: to evaluate the relation between breastfeeding and postpartum weight reten-tion. Methods: this prospective cohort study involved 641 newborns and their mothers, followed up to twelve months postpartum. Data were collected from June 2015 to February 2017. In the first interview, we investigated data regarding socioeconomic and demographic characteristics, obstetric history, weight, and gestational age of the infant at birth. Maternal weight and breastfeeding status were obtained at 3, 6, 9 and 12 months postpartum at the mother’s home. A descriptive analysis of maternal weight retention according to the lactation status was performed. Multiple linear regression models evaluated the effect on exclusive breastfeeding and total breastfeeding duration on maternal weight retention at 6 and 12 months postpartum, considering potential confounders. Results: 512 and 490 mothers were evaluated at six months and at twelve months post-partum, and the mean weight retention was 1.79 (SD=5.52) and 1.69 (SD=6.69) kg, respectively. Regardless of the confounders, the mean postpartum weight reduction for each day of exclusive breastfeeding was 11 (CI95%= -0.019 to -0.003) and 16 grams (CI95%= -0.026 to -0.007) for 6 and 12 months, respectively. The total maternal breastfeeding duration had the same effect. Conclusions: longer periods of exclusive breastfeeding and total breastfeeding are associated with lower postpartum weight retention.

[Anthropometric methods used in the evaluation of the postpartum weight retention: a systematic review]

This paper is a systematic review of scientific papers that studied postpartum weight retention. The identification of the studies was conducted in the Medline, Lilacs and Digital Library of Theses and Dissertations databases between 2000 until 2013. The main information evaluated was: author, year of publication, sample size, year of data collection, losses and analysis thereof, age, follow-up time, weight in the baseline and in the postpartum, assessment methods of weight retention and main results. Twenty studies were selected, of which 25% (n = 5) were national. Regarding the mode of analysis, in some works the result was analyzed in different ways as continuous and categorical. Of the selected papers, 45% (n = 9) analyzed the retained weight only continuously, 5% (n = 1) only categorically and 40% (n = 8) both ways. One of the studies used distribution in percentiles and the other evaluated continuously, categorical and by indicators of absolute and relative weight reduction. In conclusion, the results found reveal a lack of well-defined information about the forms of anthropometric measurements of women after delivery, indicating the need for developing national proposals, consistent with the reality of our population.

Relação entre a retenção de peso nos primeiros três meses pós-parto com ganho de peso e ingestão alimentar durante a gestação

Objetivos:estudar a retenção de peso em mulheres nos primeiros três meses pós-parto e sua correlação com ganho de peso gestacional (GPG) e consumo alimentar.Métodos:estudo de coorte com 61 mulheres. Aplicou-se: Questionário de Frequência Alimentar (QFA), Questionário Internacional de Atividade Física (IPAQ) e questionário referente à amamentação e dados antropométricos. Realizaram-se avaliações entre 24 e 48 horas pós-parto, 7, 15, 30 e 90 dias. A retenção de peso deu-se pela subtração entre peso aos três meses pós-parto e peso pré-gestacional. Os testes estatísticos usados foram: correlações de Pearson e Spearman, teste t de Student, de comparação múltipla com ajuste de Bonferroni e regressão linear.Resultados:a média de idade foi 28±7,0 anos, com medianas: de consumo alimentar diário na gestação de 3.670,3 kcal, GPG de 12,0 kg e retenção de peso nos primeiros três meses de 3,2 Kg. Observou-se associação significativa entre retenção de peso nos primeiros três meses pós-parto e o GPG (p<0,001) e a paridade (p<0,05). Para cada quilo ganho durante a gestação 0,8 kg foi retido nos primeiros três meses.Conclusões:a retenção de peso três meses pós-parto mostrou-se maior quanto maior o GPG durante a gestação e a paridade.
