Prevalence of chronic complication among type 2 diabetics attending primary health care centers of Al Ahsa district of Saudi Arabia: a cross sectional survey.

BACKGROUND: The morbidity and mortality related to diabetes is a great global concern. The knowledge of chronic complications of diabetes and associated co morbidity factors is very important for formulating the necessary policies and action plan. AIMS: To determine the prevalence of chronic complications and comorbidity among the type 2 diabetics attending the primary health care centers of Al Ahsa district of Saudi Arabia. MATERIAL & METHODS: This cross sectional retrospective survey was carried out on 506 type 2 diabetic patients attending the different primary health care centers of ministry of health, Al Ahsa. Data regarding the co morbidity factors and chronic complications were recorded from the health records of the selected diabetic patients. Data analysis was done by SPSS version 16. A p < 0.05 was considered significant for all statistical calculations. RESULTS: Overall 72.72% (95% CI 69.78-74.45) of the study subjects were suffering from one or more complications of diabetic mellitus. Among them 33.39% (165) were suffering from single, 25.29% (128) with two and 15% (75) from more than two complications. The overall prevalence of complication among the female subjects was significantly higher than the male (78.16%, 95% CI 76.76-84.40 Vs 65.76%, 95% CI 61.63-69.89, p=.038). The chronic complication was higher among the urban population than the rural population (77.3% 95% CI 72.88-80.26 Vs 69.78% 95% CI 66.1%-76.92%, p=.035). CONCLUSION: The result showed a high percentage of chronic complications among the diabetic patients of this region. The high percentage of obesity, hypertension and dyslipidaemia among them are important co morbidity factors which if not controlled can cause further increase in the number of chronic complications.

Prevalence and determinants of diabetic retinopathy in Al hasa region of saudi arabia: primary health care centre based cross-sectional survey, 2007-2009.

PURPOSE: To evaluate the prevalence of diabetic retinopathy (DR) in the urban and rural areas of Al Hasa region of Saudi Arabia and to determine risk factors related to DR. MATERIALS AND METHODS: This study was conducted on patient attending primary health care centers between July 2007 and June 2009. A retrospective chart review was conducted on subjects with diabetes mellitus greater than 18 years old. Ophthalmologists examined DR status through dilated pupils by using direct, indirect, and slit lamp bio-microscopy. Frequencies, percentage, and their 95% confidence intervals (CIs) were calculated. Odd's ratio was used to associate DR with possible risk factors. A P value less than 0.05 was considered statistically significant. RESULTS: The prevalence of DR among 473 diabetic subjects was 30% (95% CI: 25.80-34.20). The odd ratios (ORs) of DR among diabetic residing in an urban area was significantly higher than diabetics residing in rural areas [OR = 1.94 (95% CI of OR 0.82-2.89)]. DR was associated to the duration of diabetes (adjusted OR = 1.70), uncontrolled blood sugar level (adjusted OR = 1.96), hyperlipidemia (adjusted OR = 2.04), and hypercholesterolemia (adjusted OR = 2.80). CONCLUSIONS: DR appears to be a public health problem in the Al Hasa district of Saudi Arabia, and a planned approach is required to avoid severe visual impairment in patients with diabetes mellitus. Primary prevention and early detection could be implemented through primary health centers and non-ophthalmologists.
