Inter-Relationships of Income, Chronic Energy Deficiency, Morbidity and Hospitalization Among Adult Male Slum Dwellers of Midnapore, West Bengal, India

Abstract

A cross-sectional study of 212 adult (>18 years) male slum dwellers (mean age=34.6+/-14.4 years) of Midnapore town, West Bengal, India, was undertaken to study the inter-relationships of chronic energy deficiency (CED), monthly family income (MFI), self-reported morbidity and hospitalization due to severe illness. The mean height, weight and body mass index (BMI) of the subjects were 160.0 cm, 50.8 kg and 19.9 kg/m2, respectively. The overall frequencies of CED (BMI<18.5 kg/m2), morbidity and hospitalization were 38.2%, 34.4% and 13.7%, respectively. Based on the WHO classification, the prevalence of CED among this population was high (20-39%), indicating a serious situation. Overall, MFI was significantly (p<0.01) positively correlated with BMI (r=0.21). Linear regression analyses showed that MFI had a significant impact (t=3.08; p<0.002) on BMI. Overall, MFI explained 3.9% variation in BMI. Subjects belonging to the lowest family income group (FIG I) had the lowest mean BMI (19.1 kg/m2) and the highest rate of CED (46.3%) and morbidity (36.6%). Those in the highest family income group (FIG III) had the largest mean BMI (20.8 kg/m2) and lowest rate of CED (30.2%) and morbidity (30.2%). The highest rate (18.9%) of hospitalization was found in this group. There were significant family income group differences in mean BMI (F=3.134, p<0.05). The frequency of morbidity (24.6%) and hospitalization (11.9%) was lowest among normal BMI individuals. Morbidity was significantly higher (chi2=11.92, p=0.0026) among CED (48.2%) subjects compared with normal BMI individuals (OR=2.85; CI=1.49-5.46). Similarly, compared with normal BMI subjects, morbidity was higher (38.5%; OR=1.92; 95% CI=0.50-7.18) among overweight subjects. Hospitalization was more common among CED subjects (16.1%; OR=1.42; CI=0.58-3.45) compared with normal BMI subjects. Similarly, the frequency of hospitalization was more among overweight individuals (15.4%; OR=1.35; 95% CI=0.0-7.59). In conclusion, this study provides evidence that the frequency of CED among this population is high, indicating a serious situation. Moreover there exists strong inter-relationships between BMI, CED, MFI and morbidity.

Can mid-upper arm circumference and calf circumference be the proxy measures to detect undernutrition among elderly? Findings of a community-based survey in rural Puducherry, India

“…Undernourished elderly are more vulnerable to suffer from respiratory disease, poor quality of life, and all-cause mortality. [ 12 13 14 ] Economic dependency, lack of family support, and physical changes make elderly people vulnerable to suffer from undernutrition. Further, problems related to chewing and deglutition are considered to be the normal phenomena of geriatric life.…”

Body Status and Occupational Health Hazards of Female Workers : A Comparative Analysis

“…From our previous study [23] it has been revealed that the Fat% and other body composition increase with increase of nutritious food intake, which is indirectly correlated with family income. From The study of the other scientist [24,25] The regular physical activities as well as low diet might be the reasons for having hypotensive blood pressure in the workers.…”
