Health Consciousness During Pregnancy: the Association Between Dietary Supplementation and Lifestyle

Abstract Background Dietary supplements are recommended for pregnant women who cannot meet the daily dose through food intake, or who are at higher risk of deficiencies because of a substance abuse (e.g. smoking). Today, the preventive effect of folic acid (FoA) in the periconceptional period is evidence based, and there are studies about the positive effects of omega-3 fatty acids (n-3 FAs) during pregnancy. The aim of this study was to determine the association between FoA and n-3 FAs supplementation and health behavior - diet, physical activity, smoking - of pregnant women. Methods The cross-sectional study was conducted among women having their babies at the Department of Obstetrics and Gynecology (N = 1548). Data collection was based on self-administered questionnaire and health documentation. Uni- and multivariable logistic regression analyses were performed with IBM SPSS 26.0; the results are expressed in odds ratios (OR) and 95% confidence intervals (CI). Results Mean age of women was 31 years, most of them had university degree, nearly 90% of them lived in partnership. The prevalence of smoking during pregnancy was 6.5%, 39.8% did not consume fruits/vegetables daily, 58.5% ate fish less than weekly, 47.9% were physically inactive; 67.6% took FoA, and 30.6% n-3 FAs. FoA and n-3 FAs taking were more likely among those who ate fruits and vegetables every day (OR/CI: 1.30/1.01-1.66; 1.47/1.15-1.89) and among non-smokers (OR/CI: 1.73/1.06-2.83; 4.80/1.69-13.61), while FoA consumption associated with physical activity (OR/CI: 1.37/1.07-1.74) and n-3 FAs with fish consumption (OR/CI: 1.35/1.06-1.72). Conclusions Our results showed that a high proportion of pregnant women did not follow a healthy lifestyle, and the unhealthy behavior was significantly associated with the less frequent use of dietary supplementation. The results call the attention for the importance of counseling on healthy lifestyle and appropriate supplement use before and during pregnancy. Key messages Use of dietary supplementation is higher among pregnant women following a healthy way of lifestyle. The results reinforce the importance of lifestyle counseling during pregnant care.
