Prediction of gestational weight gain – a biopsychosocial model

Abstract

Objective: To examine the influence of health behaviours and psychological well-being on gestational weight gain using a biopsychosocial model. Design: A prospective cohort study of pregnant women consecutively recruited at their first antenatal care visit. A self-administered questionnaire was used to collect data on health behaviours and psychological well-being in early pregnancy. Linear regression and logistic regression were used to identify predictors of total weight gain in kilograms and weight gain outside the current Institute of Medicine recommendations, respectively. Setting: A maternity hospital in the Republic of Ireland. Subjects: Data on 799 women were analysed. Results: Pre-pregnant BMI ≥30·0 kg/m 2 , short stature, parity >0, decreased food intake and absence of health insurance predicted lower absolute gestational weight gain, while foreign nationality, consumption of takeaway meals more than once weekly and increased food intake predicted higher absolute gestational weight gain. Overweight and obesity, foreign nationality, increased food intake and height > 170 cm were risk factors for excessive weight gain, while antenatal depression was protective against excessive weight gain. Notably, physical activity measures were not related to the gestational weight gain outcomes. Pre-pregnancy overweight and increased food intake were the strongest predictors of excessive gestational weight gain. Conclusions: None of the psychological well-being measures examined, with the exception of antenatal depression, was associated with any of the weight gain outcomes. The behavioural predictors of gestational weight gain were increased food intake and takeaway consumption. Public health promotions should target pre-pregnancy BMI and pregnancy-associated change in food intake.

Pre‐pregnancy body mass index, height and physical activity are associated with rate of gestational weight gain among Malaysian mothers

“…Having a higher pre‐pregnancy BMI is a well‐established determinant of excessive GWG rate . In the present study the overweight and obese women were two–threefold more likely to have excessive GWG rate, and the weight of the fetus might contribute to the excessive GWG rate among overweight and obese women.…”

Two systematic reviews among, in total, 12 studies have been performed on the association between psychological distress and weight gain in pregnancy.…”

Addressing cultural, racial and ethnic discrepancies in guideline discordant gestational weight gain: a systematic review and meta-analysis

“…Despite the availability of these guidelines, only 30–40% of women are reported to gain within the recommended range; with most exceeding the guidelines (McDonald et al., 2011). Predictors of GWG include: pre-pregnancy weight; (Masho, Bishop & Munn, 2013; Rosal et al., 2016) socioeconomic status (SES); maternal health behaviours; (Ota et al., 2011; Heery et al., 2015) maternal age and parity (Vahratian, 2009). To date, the associations reported between race/ethnicity and discordant GWG have been diverse,(Shieh & Wu, 2014; Liu et al., 2014) likely a result of the variability in the definition of race/ethnicity and the social contexts in which they are examined.…”
