Associations of dietary methyl donor nutrients with common psychological conditions (depression, anxiety and stress) among reproductive-aged women in Kabul, Afghanistan

BACKGROUND: Higher levels of methyl donor nutrients may be associated with better psychological conditions. Little is known about the association of methyl donor nutrients with psychological conditions among women especially in Asian countries such as Afghanistan. METHOD: This cross-sectional study was conducted in Kabul, Afghanistan to assess the association of methyl donor nutrients with common psychological conditions (depression, anxiety and stress) among reproductive-aged women using multistage random sampling to choose one health center from each municipality out of four cardinal directions. Finally a sample of 421 reproductive-aged women with a mean BMI of 23.3 ± 5.0 kg/m2 and an age range of 15–45 years were collected. All women’s dietary intakes were obtained using a 24-recall questionnaire. Depression, Anxiety and Stress Scale − 21 Items (DASS-21) was used to assess psychological conditions. Chi-square tests and one-way ANOVAs were performed to assess general characteristics. Residual model test while adjusting for energy intake was used to assess nutrient intake of methyl donor nutrients and food groups. We fitted logistic regression models to assess risk for Common mental health problems (CMHPs) based on methyl donor tertiles. RESULT: We observed that there is no significant association between methyl donor nutrients and psychological disorders in both crude and adjusted models (depression, OR = 0.95, CI: 0.48; 1.88; anxiety, OR = 0.88, CI: 0.43, 1.79; stress, OR = 0.73, CI: 0.38, 1.40), (p > 0.05). CONCLUSION: Overall, we did not find any significant association between methyl donor nutrients and depression, anxiety and stress.
