Effect of Demographic Status and Lifestyle Habits on Glycaemic Levels in Apparently Healthy Subjects: A Cross-Sectional Study

الملخص EN

Aim.

To identify the effects of sociodemographic status, family history, and lifestyle habits on fasting blood glucose (FBG) and fasting serum insulin (FSI) levels in apparently healthy subjects.

Methods.

Information was gathered using an interviewer-administered questionnaire from 227 apparently healthy nondiabetic subjects residing in a suburban area in Sri Lanka.

Venous blood samples were collected after an overnight fast for FBG and FSI analysis.

Correlations and differences were analyzed using SPSS (ver.

17) software.

Results.

The majority of the subjects were females, having secondary or tertiary education, monthly income ≥Rs.

25,000 (USD 175), and a positive family history of diabetes.

Among the subjects, 10.1% were identified as prediabetics and the majority had familial diabetes with monthly income ≥Rs.

25,000 (USD 175).

Subjects with high income had significantly higher mean FBG.

In addition FBG had a significant correlation with age.

Males and subjects with less than 6 hours/day sleeping duration at night had significantly higher FBG.

Subjects with less vigorous physical activity and longer sitting duration had significantly higher FSI levels.

Conclusions.

Increasing age, higher income, positive familial history of diabetes, sedentary lifestyle, and short sleep at night have positive impact on glycaemic status in apparently healthy subjects.
