High rates of undiagnosed and uncontrolled hypertension upon a screening campaign in rural Rwanda: a cross-sectional study.

BACKGROUND: Hypertension remains the major risk factor for cardiovascular diseases (CVDs) worldwide with a prevalence and mortality in low- and middle-income countries (LMICs) among the highest. The early detection of hypertension risk factors is a crucial pillar for CVD prevention. DESIGN AND METHOD: This cross-sectional study included 4284 subjects, mean age 46 ± 16SD, 56.4% females and mean BMI 26.6 ± 3.7 SD. Data were collected through a screening campaign in rural area of Kirehe District, Eastern of Rwanda, with the objective to characterize and examine the prevalence of elevated blood pressure (BP) and other CVD risk factors. An adapted tool from the World Health Organization STEPwise Approach was used for data collection. Elevated BP was defined as ≥ 140/90 mm/Hg and elevated blood glucose as blood glucose ≥ 100 mg/dL after a 6-h fast. RESULTS: Of the sampled population, 21.2% (n = 910) had an elevated BP at screening; BP was elevated among individuals not previously known to have HTN in 18.7% (n = 752). Among individuals with a prior diagnosis of HTN, 62.2% (n = 158 of 254) BP was uncontrolled. Age, weight, smoking, alcohol history and waist circumference were associated with BP in both univariate analyses and multivariate analysis. CONCLUSION: High rates of elevated BP identified through a health screening campaign in this Rwandan district were surprising given the rural characteristics of the district and relatively low population age. These data highlight the need to implement an adequate strategy for the prevention, diagnosis, and control of HTN that includes rural areas of Rwanda as part of a multicomponent strategy for CVD prevention.

Assessing factors associated with compliance to preventive measures of COVID-19 in Rwanda: a cross-sectional community survey.

OBJECTIVE: To assess the level of compliance with COVID-19 preventive measures and compliance-associated factors in the Rwanda community. DESIGN: Cross-sectional study. SETTINGS: Country-wide community survey in Rwanda. PARTICIPANTS: 4763 participants were randomly sampled following the sampling frame used for the recent Rwanda Demographic Health Survey. Participants were aged between 22 years and 94 years. OUTCOMES: The participants' compliance with three preventive measures (wearing a face mask, washing hands and social distancing) was the main outcome. METHODS: From 14 February 2022 to 27 February 2022, a cross-sectional survey using telephone calls was conducted. Study questionnaires included different questions such as participants' demographics and compliance with COVID-19 preventives measures. Verbal consent was obtained from each participant. The compliance on three main preventive measures (wearing a mask, washing hands and social distancing) were the main outcomes. Univariate and multivariable logistic regression analyses were performed to evaluate factors associated with compliance (age, gender, level of education, socioeconomic status). RESULTS: Compliance with the three primary preventive measures (washing hands 98%, wearing a mask 97% and observing social distance 98%) was at a rate of 95%. The respondents' mean age was 46±11 SD (range 22-98) years. In addition, 69% were female and 86% had attended primary education. Bivariate and regression analyses indicated a significant association among the three primary preventive measures (p<0.05). The results showed factors associated significantly between the different models (p<0.05): proper mask use and social distancing in the hand washing model; hand washing, social distancing, avoiding handshakes and not attending gatherings in the proper mask use model; hand washing and avoiding handshakes in the social distancing model. CONCLUSION: Compliance with the three key preventive measures against COVID-19 was high in the Rwandan community and these measures were interdependent. Therefore, the importance of all three measures should be emphasised for effective disease control.

Breast Cancer Screening Participation of Women with Chronic Diseases in Korea: Analysis of the 2012 Korean National Health and Nutrition Examination Survey

Chronic disease morbidity is a concern for cancer research. Contradictory results have been reported concerning adherence to breast cancer screening among patients with chronic diseases. The study was conducted to assess the adherence to breast cancer screening among women with chronic diseases in Korea. It was a cross sectional and population based study; the data came from the Korean National Health and Nutrition Examination Survey (KNHANES) 2012. Participation in breast cancer screening was analyzed among women who had at least one of eight chronic diseases (hypertension, diabetes, cancer, dyslipidemia, stroke, depression, osteoarthritis and asthma). Pearson's chi-squared test and multiple logistic regression analysis were performed using STATA version 14. A total 2,404 women aged 40 years or older were included in analysis. Among them, 77.3% had experienced breast cancer screening. In logistic regression model, adherence to breast cancer screening was lower in women who have ever been diagnosed as diabetes mellitus (odds ratio (OR)= 0.47, 95% confidence interval (95%CI) = 0.31-0.72), asthma (OR=0.44, 95%CI=0.24-0.82) and higher in women who have ever been diagnosed as dyslipidemia (OR= 1.85, 95%CI= 1.27-2.69), osteoarthritis (OR= 1.42, 95%CI= 1.31-2.06) and cancers (OR= 2.70, 95%CI= 1.26-5.79) compared to women without those chronic diseases. Based on treatment of chronic diseases, lower participation in breast cancer screening was observed in women who were on treatment of diabetes mellitus (OR= 0.48, 95%CI= 0.31-0.74), asthma (OR= 0.41, 95%CI= 0.15-0.92) and stroke (OR= 0.37, 95%CI= 0.14-0.97), and higher in women who were on treatment of dyslipidemia (OR= 1.37, 95%CI=1.42-2.14). In conclusion, low participation rate in breast cancer screening in women with some chronic diseases was identified. The results from this study may provide an important contribution for helping to maintain and increase participation in cancer screening of patients with chronic diseases.
