Underweight body mass index is a risk factor of mortality in outpatients with nocturia in Japan

Correlates of the double burden of malnutrition among women: an analysis of cross sectional survey data from sub-Saharan Africa

OBJECTIVE

To investigate the correlates of the double burden of malnutrition (DBM) among women in five sub-Saharan African countries.

DESIGN

Secondary analysis of Demographic and Health Surveys (DHS). The outcome variable was body mass index (BMI), a measure of DBM. The BMI was classified into underweight (BMI <18.50 kg/m²), normal weight (18.50-24.99 kg/m²), overweight (25.0-29.9 kg/m²) and obesity (≥30.0 kg/m²).

SETTINGS

Ghana, Nigeria, Kenya, Mozambique and Democratic Republic of Congo (DRC).

SUBJECTS

Women aged 15-49 years (n=64698).

RESULTS

Compared with normal weight women, number of years of formal education was associated with the likelihood of being overweight and obese in Ghana, Mozambique and Nigeria, while associated with the likelihood of being underweight in Kenya and Nigeria. Older age was associated with the likelihood of being underweight, overweight and obese in all countries. Positive associations were also observed between living in better-off households and overweight and obesity, while a negative association was observed for underweight. Breastfeeding was associated with less likelihood of underweight in DRC and Nigeria, obesity in DRC and Ghana, overweight in Kenya and overweight and obesity in Mozambique and Nigeria relative to normal weight.

CONCLUSIONS

Our analysis reveals that in all the countries, women who are breastfeeding are less likely to be underweight, overweight and obese. Education, age and household wealth index tend to associate with a higher likelihood of DBM among women. Interventions to address DBM should take into account the variations in the effects of these correlates.

Analysis of the Prevalence and Factors Associated with Nocturia in Adult Korean Men

This study investigated the prevalence of and factors associated with nocturia in Korean men. A total of 92,626 participants aged between 19 and 103 years from the 2011 Korean Community Health Survey (KCHS) were enrolled. Simple and multiple logistic regression analyses with complex sampling investigated participants’ personal health and socioeconomic and disease factors. The prevalence of nocturia ≥1 time and ≥2 times/night was 41.8% and 17.6%, respectively, and nocturia increased with age (1.44 [1.39–1.50] for each 10-year increase, P < 0.001). Lower income levels (lowest, 1.27 [1.19–1.36]; low-middle, 1.13 [1.07–1.19]; upper-middle, 1.00 [0.95–1.06], P = 0.022) and higher levels of stress (severe, 1.38 [1.23–1.55]; moderate, 1.23 [1.16–1.31]; some, 1.11 [1.05–1.16]) exhibited dose-dependent relationships with nocturia (≥1 time; P < 0.001). Low education level (1.27 [1.20–1.36]), long sleep duration (1.33 [1.18–1.50]), and type of occupation showed significant associations with nocturia (≥1 time; P < 0.001). Underweight (1.19 [1.05–1.34]), hypertension (1.09 [1.03–1.15]), diabetes mellitus (1.32 [1.23–1.41]), hyperlipidaemia (1.28 [1.20–1.35]), and cerebral stroke (1.63 [1.40–1.89]) were significantly related to nocturia (≥1 time; P < 0.001). Married men were less likely to experience nocturia ≥2 times per night (0.72 [0.64–0.82], P < 0.001).
