Using fuzzy logistic regression for modeling vague status situations: Application to a dietary pattern study

Abstract Background: Adolescence is a period transition from childhood to adulthood , in which they undergo various rapid changes from physical appearances to changes in the food habits. During this period, childbearing age starts, particularly for women, which is one of the most precarious time wherein optimum nutritional status need to be achieved. So, Eating healthy during adolescence is important as rapid physical growth increases the need of several nutrients.Methods: In our study, we have used the UDAYA longitudinal study design which provides a unique opportunity to determine the role of dietary pattern at one time point to the changes at the time 2. For analysis, cross-tabulation and chi-square test is used to test independence of various groups. Binary logistic regression is used to identify determinants of minimum dietary diversity (Yes=1, No=0) of the adolescents. Adjusted odds ratio are computed for Uttar Pradesh and Bihar separately, as well as for combined sample.Results: In the present study, the average adherence to the dietary pattern in our adolescents was 58%, while in Bihar it was 61% , and in UP it was 56%. Using the logistic regression analysis, we found that there was significant difference in the MDD of adolescents by their socio-economic characteristics. But no differentials were found among young and old adolescents in UP and Bihar. Also, food consumption score index (A.O.R.=2.6, 95% CI (2.1-3.1), and media exposure of adolescents at wave1 (A.O.R.=2.1, 95% CI (1.7-2.7) were found significant in depicting the MDD at wave2. Conclusions: India launched ICDS scheme in 1975s to strengthen the nutritional status of young children in the country, but the recent data of NFHS-5 (2019-20), shows that the nutritional status of the country improved only marginally, or rather decreased in some parts. Strengthening and proper evaluation of ICDS programme can help to improve the pro-nutrition among the adolescents. Also, there should be a specific state policy to address the needs of adolescents, and various educational programmes should be conducted in schools where students along with their parents should be educated about the need of healthy dietary habits.

Ethiopian Orthodox

About half of Ethiopians belong to the Orthodox Tewahedo religion. Annually, more than 200 days are dedicated to religious fasting, which includes abstaining from all types of food, animal source foods, and water. However, the association of fasting with undernutrition remains unknown in Ethiopia. Therefore, dietary pattern and nutritional status of lactating women during lent fasting and non-fasting periods were studied, and predictor variables for maternal underweight were identified. To achieve this, lactating mothers in lent fasting (N = 572) and non-fasting (N = 522) periods participated from rural Tigray, Northern Ethiopia. Average minimum diet diversity (MDD-W) was computed from two 24-h recalls, and nutritional status was assessed using body mass index (BMI). Binary logistic regression was used to identify potential predictors of maternal underweight. Wilcoxon signed-rank (WSRT) and McNemar’s tests were used for comparison of the two periods. The prevalence of underweight in fasting mothers was 50.6%. In the multivariate logistic regression model, younger age, sickness in the last four weeks preceding the survey, fasting during pregnancy, lactation periods, grandfathers’ as household decision makers, previous aid experience, non-improved water source, and not owning chicken were positively associated with maternal underweight. In WSRT, there was no significant (p > 0.05) difference on maternal body weight and BMI between periods. The average number of meals, diet diversity, and animal source foods (ASFs), consumption scores were significantly increased in non-fasting compared to fasting periods in both fasting and non-fasting mothers (p < 0.001, p < 0.05, and p < 0.001, respectively). Consumption of dark green leafy vegetables was higher in the fasting period (11%) than non-fasting (3.6%), in the study population. As a conclusion, Ethiopian Orthodox fasting negatively affected maternal nutritional status and dietary pattern in rural Tigray, Northern Ethiopia. To reduce maternal malnutrition in Ethiopia, existing multi-sectoral nutrition intervention strategies, should include religious institutions in a sustainable manner.
