Risk factors of anemia amongst elderly population living at high-altitude region of India

INTRODUCTION: Anemia is a major public health problem amongst elderly population in India. Anemia in old age further worsens the age-related decline in functional ability, mobility, fatigue, bone density, and skeletal muscle mass. There is lack of evidence on the prevalence and risk factors of anemia among elderly population. Hence, this study was undertaken. METHODOLOGY: A community-based cross-sectional study was conducted during the year 2015–2016 in District Nainital, Uttarakhand state, India. A total of 958 subjects were selected from 30 clusters (villages) identified using population proportional to size methodology. Information on sociodemographic profile, nutritional status, body mass index, and dietary intake was obtained. Blood sample was collected from each subject on the filter paper for estimation of hemoglobin (Hb) level using cyanmethemoglobin method. RESULTS: We found that 92.1% of the elderly subjects were anemic. Moderate and severe anemia was found to be significantly higher among female subjects, unemployed, illiterates, subjects using smoke-producing fuel, subjects belonging to lower socioeconomic status, malnourished and underweight subjects, subjects with self-reported hyperacidity, and subjects who had not utilized health facility and had lower iron and vitamin C intake when compared with subjects with mild anemia and normal hemoglobin levels. CONCLUSION: High prevalence of anemia exists amongst elderly subjects living at high-altitude region of rural Uttarakhand State, India. There is a need to educate the elderly population about the importance of adequate intake of foods rich in iron and vitamin C to reduce the prevalence of anemia among them.
