    Waist circumference, waist-to height ratio, or body mass index: which is the better predictor of hypertension in patients living with diabetes mellitus in low-to-middle-income countries?
    (2022) Konar, Kylie Divashnee.; Pillay, Somasundram.
    Background Hypertension (HPT) in low and middle-income countries (LMICs) remains a leading preventable factor for death and disability. Approximately 20-60% of patients living with diabetes (PLWD) have HPT which doubles the mortality risk and accelerates the progression of complications. Obesity is a well-known preventable risk factor for HPT. Despite this, countries in Sub-Saharan Africa (SSA) faces an increasing challenge of obesity. Current evidence on anthropometric indices as a predictor for HPT in PLWD remain unclear. Methods A scoping review was performed to determine the association between anthropometry and HPT in PLWD in LMICs in SSA, by using PubMed, Google, Scopus and Cochrane between 2011- 2021. A total of 4590 records were identified. The associations between body mass index (BMI), waist circumference (WC) or waist-to-height ratio (WTHR) in PLWD and HPT in LMICs in SSA were assessed. Results We analyzed 21 studies with 11 057 patients included in this review. BMI was the most common anthropometric index used with more than 80% of studies suggesting a positive association with HPT. Varying associations between other anthropometric indices and HPT were found. Conclusions Our scoping review highlighted a positive association between HPT and anthropometry in most studies. Limited data was available comparing the different anthropometric indices. We found that additional studies are warranted to evaluate anthropometric indices in PLWD.
