Objective Overweight and obese adults are at high risk for developing prediabetes and diabetes. The aim of this study was to measure the prevalence of prediabetes (pre-DM) and diabetes (DM) among Yemeni adults who were overweight or obese and had first-degree relatives with DM, consanguinity and other risk factors. Patients and Methods This cross-sectional study included 612 adults, all with a BMI≥25 kg/m2. BMI, blood pressure (BP) and waist circumference (WC) were measured in the clinic. Fasting blood glucose (FBG) was collected for all subjects. The patients either had first-degree relatives with diabetes or not, and the subjects answered a questionnaire regarding the consanguinity of their parents, exercise, khat chewing, smoking, and eating vegetables and fruits daily. Results Of the 612 study participants (32% males and 68% females) aged 20–70 years old, 429 (70.1%) had a family history (FM) of DM ± consanguinity of parents, and 183 (29.9%) had no FM of diabetes. Multivariate analysis showed significant risk in those with class III obesity for pre-DM (AOR 3.10 95% CI 1.56–6.18 p value 0.001) and DM (AOR 3.35 95% CI 1.47–7.65 p value 0.004) and those who had siblings with DM had a risk for pre-DM (AOR 1.72 95% CI 1.09–2.71 p value 0.02) and DM (AOR 2.24 95% CI 1.25–4.0 p value 0.007). Khat chewing increased the risk for pre-DM (AOR 1.61 95% CI 1.04–2.48 p value 0.032) and for DM (AOR 2.09 95% CI 1.14–3.82 p value 0.017). Having consanguineous parents plus siblings with DM were associated with a higher risk of DM (p value 0.031). Conclusion There is a high prevalence of pre-DM and undiagnosed DM among overweight and obese Yemeni individuals. Class III obesity, having siblings with DM, chewing khat, and having consanguineous parents plus siblings with DM all increased the risk. This group should be screened at an early age for early detection of pre-DM and DM.
