Background: Although non-communicable disease (NCD) risk factors are well documented individually, their clustering phenomenon has not adequately been studied in the elderly population. This study assessed patterns and predictors of NCD risk factor clustering amongst elderly.
Methods: Data of 1,178 elderly aged ≥60 years from Bangladesh NCD STEPs survey were analyzed. The pattern of NCD risk factor clustering was assessed using principal component analysis. Sociodemographic correlates of clustering of risk factors were assessed using mixed-effects logistic regression. The association between clustering of ≥3 primary risk factors with
hypertension and diabetes was assessed using mixed-effect multivariable logistic regression, adjusting plausible confounders.
Results: Among 780 men and 398 women included in the study, the mean age was 68(±8) years. Around 58.7% were found to
have ≥3 risk factors in different permutations. Women (OR=1.5), elderly aged ≥80 years (OR=1.5) and of the richest quartile
(OR=2.96) were more likely to have ≥3 risk factor. Among males, low physical activity and smoking were found to cluster together. Among people of higher wealth quartiles, with secondary or above education, both central and general obesity showed the tendency to coexist. Clustering was found to be significantly associated with hypertension (OR=1.8) and diabetes
Conclusion: Clustering of ≥3 risk factors was highly prevalent amongst the Bangladeshi elderly. Women and elderly of higher
age bracket and of wealthiest quartile are more likely to have clustering of risk factors. The finding has the potential to guide
successful NCD prevention initiatives to improve the quality of life of the elderly.
