Evaluation of Blood Glucose Levels Among Secondary School Teachers in Kaduna State

Type 2 diabetes mellitus is a chronic metabolic disorder of growing public health significance in Nigeria, particularly among working-age adults. This study evaluates fasting blood glucose levels among secondary school teachers in Kaduna State, North West Nigeria, a group whose sedentary occupational demands and dietary patterns may predispose them to hyperglycaemia. A descriptive cross-sectional study was conducted involving 180 teachers recruited from ten randomly selected public secondary schools across three local government areas. Fasting capillary blood glucose was measured using a validated glucometer, and participants completed questionnaires assessing diet, family history of diabetes, physical activity, and use of traditional herbal remedies. Age, body mass index, and waist-to-hip ratio were also recorded. Results are expected to reveal a significant proportion of participants with impaired fasting glucose, potentially undiagnosed. The study also explores the relationship between years of teaching experience and metabolic indices, as prolonged occupational stress has been linked to insulin resistance. Findings will be compared with normative values established by the World Health Organization and the American Diabetes Association. This study contributes to early detection frameworks for type 2 diabetes in occupational groups within the North West geopolitical zone. Recommendations for workplace health screening and lifestyle modification programmes are proposed. Keywords: blood glucose, diabetes screening, teachers, Kaduna State, fasting hyperglycaemia.
