Prevalence, Awareness, Treatment, and Control of Hypertension among Young and Middle-Aged Adults: Results from a Community-Based Survey in Rural Tanzania.

ABSTRACT: Background:Hypertension, which is the single most important risk factor for CVDs, is increasing at an alarming rate in most developing countries. This study estimated the prevalence, awareness, treatment, and control of hypertension among young and middle-aged adults in rural Morogoro, Tanzania. Furthermore, it explored factors associated with both prevalence and awareness of hypertension. Methods:A cross-sectional survey was conducted as part of the cluster randomized controlled study of community health workers (CHWs) interventions for reduction of blood pressure in a randomly selected sample of young and middle-aged population in rural Morogoro. Sociodemographics, lifestyle-related factors, history of diagnosis, and treatment for hypertension were collected using a questionnaire adopted from the STEPS survey tool. Blood pressure, height, and weight were measured at home following standard procedures. Descriptive statistics were used to estimate prevalence, awareness, treatment, and control of hypertension. Multiple logistic regression models were used to assess determinants of hypertension and awareness. Result:The prevalence of hypertension was 29.3% (95% CI: 27.7-31.0). Among individuals with hypertension, only 34.3% were aware of their hypertension status. Only around one-third (35.4%) of those who were aware of their hypertension status were currently on antihypertensive medication. Hypertension control was attained in only 29.9% among those on medications. Older age (p < 0.001), use of raw table salt (p < 0.001), and being overweight/obese (p < 0.001) were associated with hypertension. Predictors of awareness of hypertension status were older age, being a female, higher socioeconomic status, use of raw table salt, a history of diabetes, and overweight/obesity (all p < 0.001). Alcohol drinking was associated with low awareness for hypertension status (p < 0.001). Conclusion:There is high prevalence of hypertension with low rates of awareness, treatment, and control among young and middle-aged adults in rural Tanzania. Community-level health promotion and screening campaigns for hypertension and other CVD risk factors should be intensified.

Project description:ImportanceIsolated systolic hypertension (ISH) is increasing in prevalence among young and middle-aged adults. However, most studies of ISH are limited to older individuals, and a substantial knowledge gap exists regarding younger adults with ISH.ObjectiveTo assess the prevalence, awareness, and characteristics of ISH among younger and middle-aged adults in China.Design, setting, and participantsThis cross-sectional study was performed as part of the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project, which enrolled 3.1 million community residents aged 35 to 75 years from all of the 31 provinces in China between December 15, 2014, and May 15, 2019. The present analysis included only participants younger than 50 years. Data were analyzed from May to November 2019.Main outcomes and measuresPrevalence and awareness of ISH (defined as systolic blood pressure of 140 mm Hg or higher and diastolic blood pressure of less than 90 mm Hg) and individual characteristics of participants with ISH.ResultsAmong 898 929 participants aged 35 to 49 years, the mean (SD) age was 43.8 (3.9) years; 548 657 participants (61.0%) were women, and 235 138 participants (26.2%) had hypertension. Of those with hypertension, 62 819 participants (26.7%; 95% CI, 26.5%-26.9%) had ISH (mean [SD] age, 45.0 [3.5] years; 41 417 women [65.9%]), and 54 463 of those with ISH (86.7%; 95% CI, 86.4%-87.0%) had not received treatment. The prevalence of ISH was higher among individuals who were older, were female, were farmers, resided in the eastern region of China, and had an educational level of primary school or lower. Women and older individuals were more likely to have ISH than to be normotensive or to have other hypertension subtypes. Participants who were obese, currently used alcohol, had diabetes, and experienced previous cardiovascular events were more likely to have other types of hypertension and less likely to have normotension than to have ISH. Among the 54 463 participants with ISH who had not received treatment, only 3682 individuals (6.8%; 95% CI, 6.6%-7.0%) were aware of having hypertension, and awareness rates remained low even among those with systolic blood pressure of 160 mm Hg or higher (7135 individuals [13.1%; 95% CI, 12.4%-13.9%]).Conclusions and relevanceIn this study, ISH was identified in 1 of 4 young and middle-aged adults with hypertension in China, most of whom remained unaware of having hypertension. These results highlight the increasing need for better guidance regarding the management of ISH in this population.

Project description:BackgroundImproving cardiovascular health requires public knowledge and reduction of modifiable cardiovascular disease (CVD) risk factors. This study assessed knowledge of risk factors and warning signs for CVDs among young and middle-aged adults in Morogoro, Tanzania.MethodsWe conducted a community-based survey as part of cluster randomized controlled study of community health workers (CHWs) intervention for reduction of blood pressure among young and middle-aged adults in rural Morogoro. Information on socio-demographic characteristics, knowledge of risk factors and warning signs for CVDs was collected using an interviewer administered questionaire. Knowledge was assessed using open-ended questions followed by closed-ended questions. Descriptive statistics were used to describe knowledge of risk factors and warning signs. Logistic regression analysis was used to investigate factors associated with adequate knowledge of risk factors and warning signs for CVDs.ResultsTwo-thirds (65.7%) of the participants had heard about CVDs. The main sources of information were mainly relatives/ neighbors (64.8%) and radio (53.0%). Only 28.3% of the participants reported health care providers as source of information about CVDs. More than half of the participants (52.4%) did not mention even one risk factor spontaneously while 55.2% were unable to mention any warning sign. When asked to select from a list, 6.9% were unable to correctly identify any risk factor whereas 11.8% could not correctly identify even a single warning sign. Quarter of participants (25.4%) had good knowledge score of risk factors, 17.5% had good knowledge score of warning signs and 16.3% had overall good knowledge of both risk factors and warning signs. Residing in Ulanga, having higher education level, having ever checked blood pressure and being overweight/obese predicted adequacy of knowledge score for both risk factors and warning signs.ConclusionKnowledge of risk factors and warning signs in this rural population of young and middle-aged adults was generally low. Health care providers were less likely to provide health education regarding risk factors and warning signs for CVDs. Health promotion interventions to increase population knowledge of risk factors and warning signs should be implemented for successful reduction of CVDs in Tanzania.
