Knowledge of obesity related pregnancy risks among expectant mothers and its associated factors

Obesity in pregnancy causes both maternal and foetal complications hence adequate knowledge of obesity related pregnancy risks would ensure better outcomes. This study aims to determine the knowledge of obesity related pregnancy risks among pregnant women.

A cross-sectional study was conducted among pregnant women from four antenatal clinics in Seremban, between February and May 2015. Knowledge on pregnancy risks was assessed using questionnaire. Women were defined as having broad knowledge on obesity related pregnancy risks if they correctly identified that women who are very obese, are at higher risk of obesity related pregnancy complications and weight loss prior to pregnancy is associated with lower risk of obesity related pregnancy complications. Descriptive statistics and regression tests were used in the analysis.

A total of 315 women participated in this study. Their mean age is 29.3 (SD±4.8) years and majority were Malay (72.4%). More than half of them were overweight and obese (60.6%). About 63.2% participants had broad knowledge on obesity related pregnancy risk. Education is a significant predictor of broad knowledge as women with tertiary education had higher odds of having broad knowledge compared to those with only school education (OR 2.1; 95%CI: 1.28 to 3.59).

This study found that more than half of the participants had knowledge of obesity related pregnancy risks and that education is a significant predictor for knowledge. Pre-pregnancy care education programmes can help identify barriers, introduce simple weight management strategies to overcome obesity, to ensure better maternal and foetal outcome.
