Andersen's model on determining the factors associated with antenatal care services in Nepal: an evidence-based analysis of Nepal demographic and health survey 2016.

BACKGROUND: With the formulation of the National Safe Motherhood Policy in 1998, safe motherhood has forever been a priority program in Nepal. Under the safe motherhood program, every woman is provided with essential maternal health care services until now through the four-tire district health care system. There is a considerable increase in the utilization of antenatal care (ANC) by a skilled health provider from 2011 to 2016, 58 to 84%, respectively. However, inequality, exclusion, and under-utilization in health care services continue in many regions of Nepal. The present study aimed to explore the different types of socio-demographic factors associated with current ANC service utilization in Nepal. METHODS: A cross-sectional study was conducted using the Nepal Demographic and Health Surveys data (DHS-7, 2016-2017). We estimated the latest pregnancy and live births in recent 5 years with the utilization of ANC services, and socio-economic differentials in these indicators under the framework of the Andersen behavioral model. RESULTS: Two in three (69.8%) with last birth accessed at least four ANC visits. The rate of live birth was about 98.6% in the ANC4+ group, higher than that of 96.8% in the ANC4- group (χ2: 14.742, P <  0.001). In the multilevel logistic regression analysis, we found that women from province 2 (OR: 0.48; 95%CI: 0.32-0.74) and province 6 (OR: 0.46; 95%CI: 0.30-0.71) were significantly less likely to visit ANC 4 or more times. Age (OR: 0.95; 95%CI: 0.93-0.96) was also significantly associated with the frequency of ANC visits. Level of Women's education and education of her partner were both significantly associated with the ANC visits: women (OR: 4.64; 95%CI: 3.05-7.05) and her partner (OR: 1.45; 95%CI: 1.01-2.06) having higher education were most likely to go for the recommended number of ANC visits. Moreover, women having exposure to multimedia were more likely to go for four or more ANC check-ups. CONCLUSIONS: The results highlight the need for governments and health care providers to develop special health promotion program with a focus on the vulnerable and disadvantaged and to use multi-media for maternal health literacy improvement flexibly, and maternal health system strengthening.

Urinary polycyclic aromatic hydrocarbons and adult obesity among the US population: NHANES 2003-2016.

Polycyclic aromatic hydrocarbons (PAHs) are naturally occurring environmental pollutants that may contribute to obesity in the adult population. To investigate the relationship between the urinary concentrations of PAH metabolites and adult obesity among the US population, the National Health and Nutritional Examination Survey (NHANES, 2003-2016) was used as a data source for this study. As many as 4464 participants in the NHANES 2003-2016 were included in the final analyses. We used logistic regression to look at the link between urinary PAH metabolites and obesity, using odds ratios (ORs) and 95% confidence intervals (CIs). The study sample comprised 4464 individuals aged ≥18 years, 2199 were male and 2265 were female. The study characteristics for four different quartiles were analyzed, and the average ages of the four urinary PAH quartiles were 49.61 ± 20.01, 46.63 ± 20.33, 44.28 ± 19.19, and 43.27 ± 17.68 years, respectively. In the quartile analysis of all participants, the third quartile was significantly associated with an increased prevalence of obesity (OR = 1.33, 95% CI = 1.12-1.59) with p-values <.05. In addition, females, but not males, had a strong link between the second, third, and fourth quartiles of urinary PAH and a higher risk of obesity (OR = 1.27, 95% CI = 1.00-1.61; OR = 1.52, 95% CI = 1.19-1.94; and OR = 1.39, 95% CI = 1.09-1.78). In conclusion, the study observed that urinary PAH metabolites were associated with the prevalence of obesity among the US population.

Breastfeeding Perceptions and Decisions among Hispanic Participants in the Special Supplemental Nutrition Program for Women, Infants, and Children: A Qualitative Study.

The Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is a nutrition assistance program in the U.S. WIC served 2.5 million eligible Hispanic women, infants, and children under the age of five in 2021, which is WIC's largest racial/ethnic group. However, limited research has been conducted to understand Hispanic WIC participants' perceptions of WIC breastfeeding recommendations and their breastfeeding decisions. For this qualitative study, we interviewed 18 of these pregnant and postpartum WIC participants on their experiences and decision-making processes related to breastfeeding. Hispanic cultures and home country norms were identified as prominent influences on breastfeeding decisions, along with perceptions of WIC's breastfeeding support. These results can help the WIC program to refine its breastfeeding education to better meet the needs of Hispanic participants.

Psychometric properties of Nepalese preschool anxiety scale among preschool children: A cross-sectional study.

Background: The Preschool Anxiety Scale (PAS)-Parent version scale is a 28-item measure designed to assess anxiety symptoms in preschoolers aged 3-6 years. The aim of this study was to assess the psychometric properties of the Nepali translated version of the PAS-Parent version. Methods: A descriptive cross-sectional design was used to collect data from 680 mothers among seven conveniently selected schools in Kathmandu. Results: The difference in PAS-Parent version scores across age groups was found to be statistically significant. In confirmatory factor analysis, 28 items showed a poor fit of the five-factor original model for the data. However, removing three items (25 item version) through the five-factor model indicated a better fit. Internal consistency measured by Cronbach's α for the PAS-Parent version scale was of good range (0.87). Cronbach's α of the subscales: generalized anxiety (0.63), social phobia (0.67), physical injury fears (0.75), and separation anxiety (0.63) were in fair range; while it was in poor range for the obsessive-compulsive subscale (0.567). Conclusion: Nepali version of the PAS demonstrated fair psychometric properties, supporting its utility in screening and assessing a broad range of anxiety symptoms in Nepalese preschoolers.

A Multilevel Analysis to Determine the Factors Associated with Institutional Delivery in Nepal: Further Analysis of Nepal Demographic and Health Survey 2016.

BACKGROUND: One out of two neonatal deaths and 2 out of 5 maternal deaths occur at home in Nepal. An essential intervention in reducing maternal mortality and neonatal death is institutional delivery. The objective of this study was to find out the external environmental, predisposing, and enabling factors associated with the use of institutional delivery care in Nepal. METHODS: Data from Nepal Demographic and Health Surveys (NDHS) 2016 was used to estimate socio-economic, provincial, and use of media differentials with institutional delivery under the Andersen behavioral model framework using multilevel regression analysis. RESULTS: More than half of the women (60.9%) among 3899 women with last birth had their babies delivered in a health facility. In the multilevel logistic regression analysis, we found that women from province 2 (OR = 0.47 95%CI: 0.28-0.79) were significantly less likely to deliver in health institutions, and province 7 (OR = 1.76, 95%CI: 1.05-2.94) were significantly more likely deliver in a health institution. Age (OR = 0.94, 95%CI: 0.92-0.95) was also significantly associated with the place of delivery. Women with higher education (OR = 3.17, 95%CI: 2.09-4.81) were most likely to go for institutional delivery. The odds of women opting for institutional delivery were 3 folds more for those who had visited Antenatal Care (ANC) 4 or more times compared to those who did not. CONCLUSION: The results highlight the need for governments and health care providers to emphasize the promotion of institutional delivery and ANC visits as per protocol with a special focus on underprivileged communities. The use of multi-media is a vital strategy to promote the use of institutional delivery services.

Causal effects of dietary calcium, zinc and iron intakes on coronary artery disease in men: G-estimation and inverse probability of treatment weighting (IPTW) analyses.

BACKGROUND & AIMS: Dietary minerals have significant effects on the risk of cardiovascular disease. However, the results of previous studies were not uniform across different countries. The current study aims to determine the causal effects of dietary calcium, zinc, and iron intakes on coronary artery disease (CAD) among Nepalese men. METHODS: A matched case-control study was carried out at Shahid Gangalal National Heart Center. Dietary intakes of 466 male participants over the past 12 months were evaluated using a semi-quantitative customized food frequency questionnaire. G-estimation and inverse probability treatment weighting (IPTW) analyses were performed to determine the causal odds of CAD due to dietary calcium, zinc, and iron intakes. RESULTS: Daily dietary calcium, zinc, and iron intakes were categorized into two groups: less than versus more than the median value and less than versus equal or more than recommended daily allowance (RDA). In G-estimation, dietary calcium intake was inversely associated with CAD in both medians (OR: 91; 91%CI: 0.86, 95) and RDA categories (OR: 0.88: 95%CI: 0.84, 0.97). However, in IPTW analysis, only median calcium intake was significantly associated with CAD (OR: 7; 91%CI: 0.5, 98). We observed a significant inverse association of equal or more than RDA of dietary zinc intake with CAD (OR: 0.91: 95%CI: 0.87, 0.96 in G-estimation, OR: 0.73: 95%CI: 0.66, 0.82 in IPTW); however, more than median dietary zinc intake showed inverse but not significant association with CAD in both analyses. Dietary iron intake was inversely but not significantly associated with CAD in G-estimation in both groups. Nevertheless, in IPTW analysis, equal or more than RDA iron intake was significantly positively (OR: 1.4; 95%CI: 1.14, 1.73) related to CAD. CONCLUSIONS: A significant inverse association of dietary zinc intake above RDA indicates the potential protective effect of higher dietary zinc against CAD. However, causal odds of CAD are inconsistent across the median or RDA of calcium and iron intakes. Therefore, cohort and randomized clinical trial studies with a large sample size are recommended to substantiate these nutrients' causal link with CAD development in the Nepalese population.

Dietary nutrients of relative importance associated with coronary artery disease: Public health implication from random forest analysis.

Dietary nutrients have significant effects on the risk of cardiovascular diseases. However, the results were not uniform across different countries. The study aims to determine the relative importance of dietary nutrients associated with coronary artery disease (CAD) among the Nepalese population. A hospital-based matched case-control study was carried out at Shahid Gangalal National Heart Center in Nepal. In the present study, patients with more than seventy percent stenosis in any main coronary artery branch in angiography were defined as cases, while those presenting normal coronary angiography or negative for stressed exercise test were considered controls. Dietary intakes of 612 respondents over the past 12 months were evaluated using a semi-quantitative customized food frequency questionnaire. In conditional regression model, the daily average dietary intake of ß-carotene (OR: 0.54; 95%CI: 0.34, 0.87), and vitamin C (OR: 0.96; 95%CI: 0.93, 0.99) were inversely, whereas dietary carbohydrate (OR: 1.16; 95%CI: 1.1, 1.24), total fat/oil (OR: 1.47; 95%CI: 1.27, 1.69), saturated fatty acid (SFA) (OR: 1.2; 95%CI: 1.11, 1.3), cholesterol (OR: 1.01; 95%CI: 1.001, 1.014), and iron intakes (OR: 1.11; 95%CI: 1.03, 1.19) were positively linked with CAD. Moreover, in random forest analysis, the daily average dietary intakes of SFA, vitamin A, total fat/oil, ß-carotene, and cholesterol were among the top five nutrients (out of 12 nutrients variables) of relative importance associated with CAD. The nutrients of relative importance imply a reasonable preventive measure in public health nutrients specific intervention to prevent CAD in a resource-poor country like Nepal. The findings are at best suggestive of a possible relationship between these nutrients and the development of CAD, but prospective cohort studies and randomized control trials will need to be performed in the Nepalese population.
