Abstract This study aimed to determine the prevalence of abnormal fasting blood glucose levels and identify associated risk factors among adults in a rural community in southeastern Nigeria. A community-based, cross-sectional screening study was conducted among 200 adults aged ≥18 years in Okija, Anambra State, Nigeria. Participants were recruited through voluntary participation during a community health outreach program. Fasting blood glucose was measured using capillary blood obtained via finger prick with a calibrated portable glucometer following overnight fasting. Anthropometric indices, including body mass index (BMI) and waist circumference, were recorded. Demographic and lifestyle data were collected using a structured questionnaire. Twenty-four participants (12.0%) had fasting blood glucose levels consistent with possible diabetes, while 59 (29.5%) had impaired fasting glucose (prediabetes), with 83 (41.5%) participants exhibiting abnormal glucose regulation. Elevated fasting blood glucose levels were significantly associated with age group (χ2 = 17.61, df = 7, p = 0.020), waist circumference (χ2 = 4.79, df = 1, p = 0.029), carbohydrate intake (χ2 = 4.50, df = 1, p = 0.034), and fat intake (χ2 = 6.14, df = 1, p = 0.013). There is a high burden of abnormal fasting blood glucose levels and prediabetes in this rural population. Community-based screening and targeted lifestyle interventions are essential to reduce the growing burden of diabetes.
