Among 62 adults aged 60+ (mean age 74) residing in a state social-care facility in Astana, Kazakhstan, a striking cardiometabolic profile emerged: 63% had arterial hypertension, 71% showed elevated LDL-cholesterol (≥3.0 mmol/L), and 58% were overweight or obese — yet only 5% were underweight. Dietary analysis revealed near-universal inadequacies: 92% fell short on potassium, 90% on fiber, 85% on calcium, and 71% exceeded sodium thresholds. Among 29 participants tested, 79% were vitamin D deficient, with overweight co-occurring with deficiency in 16 cases.
This finding challenges the dominant clinical assumption that institutionalized elderly populations are primarily at risk for undernutrition and wasting. Instead, it reveals a "double burden" pattern more commonly associated with low-to-middle-income urban populations — excess adiposity paired with micronutrient poverty — now documented within a formal care setting. The sodium-potassium imbalance identified is particularly clinically relevant, as this ratio is an independent cardiovascular risk driver in older adults.
However, significant limitations constrain interpretation: the sample of just 62 individuals from a single facility is far too small and geographically specific to generalize broadly. The cross-sectional design prevents causal inference, and none of 56 diet-risk correlations survived multiple-testing correction, underscoring statistical underpowering. As a preprint posted on medRxiv and not yet peer-reviewed, these findings require independent validation. Still, the study is practically valuable — it provides actionable institutional targets around fortified menus, vitamin D supplementation protocols, and cardiometabolic screening programs in Central Asian elder care.
