Association of sociodemographic, obstetric characteristics, lifestyle and food consumption with life satisfaction and optimism among overweight pregnant women.

The present study investigated the relationships between maternal characteristics and subjective well-being (life satisfaction and optimism) among overweight Brazilian adult pregnant women. A cross-sectional study utilising baseline data from a randomised controlled clinical trial was conducted. A total of 330 women were investigated. Maternal characteristics (sociodemographic, obstetric and lifestyle) were obtained through a structured questionnaire. Data on dietary intake were collected through two 24-h dietary recalls, and the usual diet was estimated using the Multiple Source Method. Life satisfaction and optimism were assessed using validated instruments. Both unadjusted and adjusted linear regression models were employed to investigate the relationship between maternal characteristics and subjective well-being. Sleep quality was found to be positively associated with life satisfaction. Miscarriage and smoking during pregnancy were negatively associated with this sentiment. Additionally, a positive association was observed between optimism and maternal characteristics such as sleep quality, desired pregnancy and alcohol consumption in the previous 30 d. Furthermore, it was found that the consumption of sugary drinks, dietary fibre and Ca were positively associated with this same feeling. The present study showed that some maternal and food consumption characteristics were associated with subjective well-being among overweight pregnant women. It is, therefore, essential to recognise predictors of maternal mental health given their relevance to the field of public health.
