Prevalence of diabetic retinopathy among diabetic patients in Northwest Ethiopia-A cross sectional hospital based study.

ABSTRACT:

Background

Diabetic retinopathy is the most common microvascular complication of diabetes mellitus on eye and it is the leading cause of visual impairment among productive segment of the population. Globally, the prevalence of diabetic retinopathy is reported to be 27%. In Ethiopia, sufficient data is lacking on the prevalence of diabetic retinopathy as well as information on its predisposing factors. The study was required to assess the prevalence of diabetic retinopathy and its predisposing factors in diabetic patients attending at a General Hospital in Ethiopia.

Methods

An institution based cross sectional study was employed on 331 diabetic patients recruited with a systematic random sampling technique. Data were collected through structured questionnaire, tracing patients' medical folder and ocular health examination. Data were analyzed with Statistical Package for Social Science Version 20. Logistic regression methods of analysis were used to figure out predisposing factors of diabetic retinopathy. Adjusted odds ratio with 95% confidence interval was used to determine the strength of association.

Result

A total of 331 diabetic patients completed the study with a response rate of 99.10%. The median duration of diabetes was 5 years. The prevalence of diabetic retinopathy was 34.1% (95%Confidence Interval (CI): 28.7%-39.3%). Low family monthly income (Adjusted Odds Ratio (AOR) = 7.43, 95% CI: 2.44-22.57), longer duration of diabetes (AOR = 1.44, 95% CI: 1.30-1.58), poor glycemic control (AOR = 4.76, 95%CI: 2.26-10.00), and being on insulin treatment alone (AOR = 3.85, 95%CI: 1.16-12.74) were independently associated with diabetic retinopathy.

Conclusion and recommendation

The prevalence of diabetic retinopathy was 34.1%, higher than national and global figures. Low family monthly income, longer duration of diabetes, poor glucose control and being on insulin treatment alone were important risk factors of diabetic retinopathy. Proper diabetes self management and early screening of diabetic retinopathy in all diabetic patients were recommended.

Project description:BackgroundCurrently 93 million people are estimated as living with diabetic retinopathy worldwide. The prevalence and risk factors of diabetic retinopathy in developed countries have been well documented; but in Ethiopia, data on prevalence and associated factors of diabetic retinopathy is lacking.ObjectiveTo determine prevalence and factors associated with development of diabetic retinopathy among diabetic patients at Arbaminch General Hospital, Ethiopia.MethodCross-sectional study design with record review of 400 diabetic patients was conducted at Arbaminch General Hospital from November to January 2015. Among 400 diabetic patients, 270 patients with baseline information and without history of hypertension at baseline were included in this study. But patients with gestational diabetes and with retinopathy at baseline were excluded from the study. Consecutive sampling technique was applied to select study participants. Data of cohorts was extracted from medical record using pre tested structured extraction check list. Data cleaning, coding, categorizing, merging and analysis carried out by STATA version 12. Descriptive statistics was done and presented accordingly. Bivariate binary logistic regression analysis was done to select potential candidates for the full model at P-value cutoff point ≤ 0.25 and multivariable binary logistic regression analysis was made to estimate the independent effect of predictors on the occurrence of diabetic retinopathy. Model diagnostic tests were done, final model fitness was checked using Hosmer and Lemeshow chi square test. Finally, statistical significance was tested at P-value <0.05.ResultPrevalence of diabetic retinopathy among diabetic patients at Arbaminch General Hospital was 13%. Adjusted analysis showed that the odds of diabetic retinopathy were statistically and significantly associated with baseline age (AOR = 6.06: 95%CI; 2.42, 15.21), baseline systolic blood pressure level (AOR = 4.38: 95%CI; 1.64, 11.68), family history of diabetes (AOR = 0.22: 95%CI; 0.08, 0.58) and duration of diabetes (AOR = 8.84: 95%CI; 3.56, 12.89).Conclusion and recommendationIn the current study, prevalence of diabetic retinopathy was 13%. Since baseline age ≥60 years, baseline systolic blood pressure level >140 mmhg, duration of diabetes ≥6 years and patients with family history of diabetes were statistically and significantly related with diabetic retinopathy, special care should be given in addition to routine care.

Project description:ObjectiveDiabetic retinopathy is an evident complication of diabetes on eye and contributes for significant portion of blindness worldwide. In Ethiopia, data are lacking on awareness and knowledge of diabetic retinopathy in diabetic patients. This study desired to assess knowledge of diabetic retinopathy and it is relating factors among diabetic patients attending at a General Hospital in Ethiopia.MethodsWe have interviewed 306 diabetic patients who were attending at Debre Tabor General Hospital. Binary logistic regression model was used to recognize associated factors to good knowledge of diabetic retinopathy. Adjusted odds ratio was used to show the power of association. A p-value of less than 0.05 was set to determine its statistical significance.ResultThe diabetic patients had a median age of 45 (range = 30) years. From the total diabetic patients, 242 (79.10%) knew that diabetes could affect the eye and 81 (26.50%) were aware of diabetic retinopathy. From those who were informed of diabetic retinopathy, 32 (39.50%) (95% confidence interval = 27.90-51.20) had good knowledge of diabetic retinopathy. High educational status (adjusted odds ratio = 4.08, 95% confidence interval = 1.00-16.50) and non-government employee (adjusted odds ratio = 0.19, 95% confidence interval = 0.05-0.70) were significantly associated with good knowledge of diabetic retinopathy. Physicians and eye doctors were the most frequent source of information for the awareness of diabetic retinopathy.ConclusionFrom the total diabetic patients recruited in the study, 39.5% of them obtained information about diabetic retinopathy and the overall knowledge was poor among them. Knowledge of diabetes can affect the eye and it causes blindness was good among majority of the participants. Higher educational status and being a non-government employee were determined to be important predisposing factors of good knowledge. It is also better to involve diabetic educators and counselors in educating diabetic patients on the serious complication of diabetes on eye.

Project description:BackgroundIntestinal Parasitic Infections are the most prevalent diseases in the world, predominantly in developing countries. It is estimated that more than two billion people are affected globally, mostly in tropical and sub-tropical parts of the world. Ethiopia is one of the countries in Africa with a high prevalence of intestinal parasites. However, there is a limited study conducted in the study area. Hence, this study was to assess the prevalence and associated factors of intestinal parasitosis among patients attending at Sanja Primary Hospital, Northwest Ethiopia.MethodsAn institutional-based cross-sectional study was conducted at Sanja Primary Hospital from January 1 to August 20, 2019. Stool samples were collected from 1240 study participants and analyzed by direct wet mount and formal ether concentration techniques. Furthermore, sociodemographic and explanatory variables were collected using a face-to-face interview. Data were entered into Epi data version 4.4.2.1 and transferred to SPSS version 23 for analysis. Bivariate and multivariate binary logistic regression models were fitted to identify associated factors of intestinal parasitic infections. Adjusted Odds Ratio (AOR) with 95% confidence interval (CI) was considered to ascertain the significance of the association.ResultsThe overall prevalence of intestinal parasitic infection was 52.9% (95% CI: 50.2%-55.5%). Entamoeba histolytica/dispar (21.5%) was the leading cause of intestinal parasitosis followed by Hookworm species (13.3%). Furthermore, the rate of double and triple parasitic infections was observed in 6.1% and 0.5% of study participants respectively. Being Illiterate (AOR: 2.87, 95% CI: 1.06-7.47, p = 0.038), swimming habits of more than 4 times a month (AOR = 2.91, 95% CI 1.62-5.24, p< 0.001) and not washing hands before a meal (AOR: 3.92, 95% CI: 1.74-8.83, p = 0.001) were the key factors significantly associated with intestinal parasitic infection.ConclusionsThe present study showed that the prevalence of intestinal parasitosis is high in the study area. Therefore, there is a need for an integrated control program, including improving personal, environmental sanitation and health education should be given to have a lasting impact on transmission.

Project description:Type 2 Diabetes Mellitus (T2DM) patients are increasingly using herbal remedies due to the fact that sticking to the therapeutic regimens is becoming awkward. However, studies towards herbal medicine use by diabetic patients is scarce in Ethiopia. Therefore, the aim of the current study was to explore the prevalence and correlates of herbal medicine use with different sociodemographic variables among type 2 diabetes patients visiting the diabetic follow-up clinic of University of Gondar comprehensive specialized hospital (UOGCSH), Ethiopia.A hospital-based cross sectional study was employed on 387 T2DM patients visiting the diabetes illness follow-up care clinic of UOGCSH from October 1 to November 30, 2016. An interviewer-administered questionnaire regarding the demographic and disease characteristics as well as herbal medicine use was completed by the study subjects. Descriptive, univariate and multivariate logistic regression statistics were performed to determine prevalence and come up with correlates of herbal medicine use.From 387 participants, 62% were reported to be herbal medicine users. The most prevalent herbal preparations used were Garlic (Allium sativum L.) (41.7%), Giesilla (Caylusea abyssinica (fresen.) (39.6%), Tinjute (Otostegia integrifolia Benth) (27.2%), and Kosso (Hagenia abyssinicaa) (26.9%). Most of herbal medicine users (87.1%) didn't consult their physicians about their herbal medicine use. Families and friends (51.9%) were the frontline sources of information about herbal medicine followed by other DM patients who used herbal medicines (28.9%).The present study revealed a high rate of herbal medicine use along with a very low rate use disclosure to the health care professionals. Higher educational status, a family history of DM, duration of T2DM and presence of DM complications were identified to be strong predictors of herbal medicine use. From the stand point of high prevalence and low disclosure rate, it is imperative for health care providers to strongly consult patients regarding herbal medicine use.
