Prevalence, Risk Factors, and Complications of Diabetes in the Kilimanjaro Region: A Population-Based Study from Tanzania.

ABSTRACT:

Background

In sub-Saharan Africa, diabetes is a growing burden, yet little is known about its prevalence, risk factors, and complications. To address these gaps and help inform public health efforts aimed at prevention and treatment, we conducted a community-based study assessing diabetes epidemiology.

Methods and findings

We conducted a stratified, cluster-designed, serial cross-sectional household study from 2014-2015 in the Kilimanjaro Region, Tanzania. We used a three-stage cluster probability sampling method to randomly select individuals. To estimate prevalence, we screened individuals for glucose impairment, including diabetes, using hemoglobin A1C. We also screened for hypertension and obesity, and to assess for potential complications, individuals with diabetes were assessed for retinopathy, neuropathy, and nephropathy. We enrolled 481 adults from 346 urban and rural households. The prevalence of glucose impairment was 21.7% (95% CI 15.2-29.8), which included diabetes (5.7%; 95% CI 3.37-9.47) and glucose impairment with increased risk for diabetes (16.0%; 95% CI 10.2-24.0). Overweight or obesity status had an independent prevalence risk ratio for glucose impairment (2.16; 95% CI 1.39-3.36). Diabetes awareness was low (35.6%), and few individuals with diabetes were receiving biomedical treatment (33.3%). Diabetes-associated complications were common (50.2%; 95% CI 33.7-66.7), including renal (12.0%; 95% CI 4.7-27.3), ophthalmic (49.6%; 95% CI 28.6-70.7), and neurological (28.8%; 95% CI 8.0-65.1) abnormalities.

Conclusions

In a northern region of Tanzania, diabetes is an under-recognized health condition, despite the fact that many people either have diabetes or are at increased risk for developing diabetes. Most individuals were undiagnosed or untreated, and the prevalence of diabetes-associated complications was high. Public health efforts in this region will need to focus on reducing modifiable risk factors, which appear to include obesity, as well as early detection that includes increasing awareness. These findings highlight a growing urgency of diabetes prevention in this region as well as the need for treatment, including management of complications.

Project description:BackgroundSubstance use among school-going adolescents increases the risk of developing mental disorders, addiction, and substance use disorders. These may lead to poor academic performance and reduced productivity, which affects adolescent lives. The study aimed to determine the prevalence of substance use and associated factors among secondary school adolescents in the Kilimanjaro region, northern Tanzania.MethodologyThe study used secondary data from a cross-sectional survey of adolescents aged 10-19 years from public secondary schools in the Kilimanjaro Region, northern Tanzania. Substance use was measured using the Global School Health Survey (GSHS) questionnaire. Categorical variables were summarized using frequencies and percentages, while numerical variables used mean and standard deviation. Multivariable logistic regression models were used to obtain odds ratios (OR) and 95% confidence intervals (CI) to determine risk factors associated with lifetime and current (within the past 30 days preceding the survey) substance use.ResultsThe lifetime and current prevalence of substance use among 3224 adolescents was 19.7% and 12.8%, respectively, while alcohol and cigarettes were commonly used. Female adolescents had lower odds of current substance use (OR = 0.63, 95%CI 0.50-0.80). Higher odds of current substance use were among adolescents who have ever had sex (OR = 4.31, 95%CI 3.25-5.71), ever engaged in a physical fight (OR = 2.19, 95%CI 1.73-2.78), ever been bullied (OR = 1.55, 95%CI 1.16-2.05), always seen alcohol advertisements (OR = 1.87, 95%CI 1.37-2.53), and adolescents whose parent/guardians rarely understood their problems (OR = 1.38, 95% CI = 1.03-1.85). Adolescents whose classmates always showed social support had lower odds of current substance use (AOR = 0.71, 95%CI 0.53-0.97). Similar factors were associated with lifetime substance users.ConclusionThe study reflects a high prevalence of substance use among adolescents in the Kilimanjaro region. Alcohol and cigarette are the most prevalent substances used. Regulatory measures are essential to limit alcohol advertisements that are media portrayed. Efforts are needed to reduce risk behaviors, such as physical violence and bullying, through peer support groups/clubs in school environments.

Project description:BackgroundTaenia solium cysticercosis/taeniosis is emerging as a serious public health and economic problem in many developing countries. This study was conducted to determine prevalence and risk factors of human T. solium infections in Mbeya Region, Tanzania.Methods and findingsA cross-sectional survey was conducted in 13 villages of Mbozi district in 2009. Sera of 830 people (mean 37.9±11.3 years (SD); 43% females) were tested for circulating cysticerci antigen (Ag-ELISA) and antibody (Ab-ELISA). A subset of persons found seropositive by Ag-ELISA underwent computed tomography (CT) scan of the brain for evidence of neurocysticercosis. Stool samples from 820 of the same participants were tested for taeniosis by copro-antigens (copro-Ag-ELISA) and formol-ether concentration technique. Cases of T. solium taeniosis were confirmed serologically by EITB assay (rES38). A questionnaire was used for identification of risk factors. Active cysticercosis by positive Ag-ELISA was found in 139 (16.7%) persons while anti-cysticercal antibodies were detected in 376 (45.3%) persons by Ab-ELISA. Among 55 persons positive for Ag-ELISA undergoing CT scan, 30 (54.6%) were found to have structures in the brain suggestive of neurocysticercosis. Using faecal analysis, 43 (5.2%) stool samples tested positive for taeniosis by copro-Ag-ELISA while Taenia eggs were detected in 9 (1.1%) stool samples by routine coprology. Antibodies specifically against adult T. solium were detected in 34 copro-Ag-ELISA positive participants by EITB (rES38) indicating T. solium taeniosis prevalence of 4.1%. Increasing age and hand washing by dipping in contrast to using running water, were found associated with Ag-ELISA seropositivity by logistic regression. Gender (higher risk in females) and water source were risk factors associated with Ab-ELISA seropositivity. Reported symptoms of chronic severe headaches and history of epileptic seizures were found associated with positive Ag-ELISA (p?0.05).ConclusionThe present study indicates T. solium infection in humans is highly endemic in the southern highlands of Tanzania.

Project description:IntroductionMental health disorders in pregnant women living with HIV are associated with poor maternal and child outcomes, and undermine the global goals of prevention of mother-to-child transmission of HIV (PMTCT). This study aimed to determine prevalence of depression and anxiety and identify factors associated with these common mental health disorders among HIV-infeced pregnant women in Tanzania.MethodsWe enrolled 200 pregnant women living with HIV from antenatal care clinics in the Kilimanjaro region. Women were eligible if they were in the second or third trimester of pregnancy and had been in PMTCT care for a minimum of one month. Data were collected via interviewer administered surveys. Participants self reported depression symptoms (Edinburgh Postnatal Depression Scale, EPDS) and anxiety symptoms (Brief Symptom Index, BSI). Multivariate logistic regression models examined factors associated with depression, anxiety, and comorbid depression and anxiety.Results25.0% of women met screening criteria for depression (EPDS ≥10). Depression was significantly associated with being single (aOR = 4.2, 95% CI = 1.1-15.5), food insecurity (aOR = 2.4, 95% CI = 1.0-6.4), and HIV shame (aOR = 1.2, 95% CI = 1.1-1.3). 23.5% of participants met screening criteria for anxiety (BSI ≥1.01). Anxiety was associated with being single (aOR = 3.6, 95%CI = 1.1-11.1), HIV shame (aOR = 1.1, 95% CI = 1.1-1.2) and lifetime experience of violence (aOR = 2.3, 95% CI = 1.0-5.1). 17.8% of the sample met screening criteria for both depression and anxiety. Comorbid depression and anxiety was associated with being single (aOR = 4.5, 95%CI = 1.0-19.1), HIV shame (aOR = 1.2, 95%CI = 1.1-1.3) and lifetime experience of violence (aOR = 3.4, 95% CI = 1.2-9.6).ConclusionDepression and anxiety symptomatology was common in this sample of pregnant women living with HIV, with a sizable number screening positive for comorbid depression and anxiety. In order to successfully engage women in PMTCT care and support their well-being, strategies to screen for mental health disorders and support women with mental illnesses are needed.

Project description:IntroductionDiabetes mellitus is one of the most common non-communicable diseases and is the fifth leading cause of death in most developing countries. Regular physical activity (PA) is strongly recommended for individuals with diabetes for its beneficial effects in improving blood glucose control and insulin sensitivity, prevention and reduction of morbidities and complications, and its cardiovascular benefits.ObjectiveTo assess the knowledge, attitude and practices of PA among patients with diabetes in the Kilimanjaro region, Northern Tanzania.Research design and methodsA cross-sectional study was conducted from June to September 2020 among 315 patients with diabetes aged 18 years and above receiving care from diabetic clinics in the Kilimanjaro region, Northern Tanzania. A systematic random sampling technique was used to select study participants who were interviewed using a modified version of the WHO-STEPS Survey for non-communicable diseases. Data were analysed using SPSS V.20. Categorical variables were summarised using frequencies and percentages, and continuous variables using means and SDs. The Χ2 test was used to compare the proportion of PA across participant characteristics.ResultsThe vast majority (94.3%) of the participants were physically active, and from our findings, most of it was contributed by work (70%) and transport-related (20%) activities. Participants had high levels of knowledge (98.4%) and positive attitudes (95.6%) towards PA. These were mainly contributed by a healthcare provider or doctors' advice (96%) on PA benefits to patients with diabetes. There was a strong statistical association (p<0.001) between knowledge and attitude towards PA with PA practice.ConclusionThe vast majority of the participants were physically active. High levels of PA were associated with a high level of knowledge and positive attitudes towards PA. Healthcare provider or doctors' advice in diabetic clinics is essential in promoting PA practice in this population and in diabetes management.
