Beh HC, Wong PF, Chew BN, Chia YC

Malays Fam Physician, 2023;18:66.
PMID: 38111833 DOI: 10.51866/oa.3l4

INTRODUCTION: The overall prevalence of hypertension is high, and many people are unaware of their condition. Screening campaigns can effectively identify this group of patients. The study aimed to determine the cost of manpower for a health campaign for detecting undiagnosed hypertension and the prevalence of hypertension.
METHOD: This cross-sectional study was conducted at two health centres. Sociodemographic characteristics, hypertension and treatment statuses were recorded. Blood pressure (BP) was measured by either doctors or nurses using automated BP machines. The cost of manpower was calculated as the average salaries of manpower during the 3-day health campaign divided by the total number of days. The final sum was the cost of detecting undiagnosed hypertension.
RESULTS: A total of 2009 participants median age = 50 (IQR = 18-91) were included in the study. The overall prevalence of hypertension was 41.4% (n=832). Among the patients with hypertension, 49.2% (n=409) were unaware of their hypertension status. Conversely, 21.1% (n=423) were known to have hypertension, among whom 97.4% (n=412) were on medications. Among those who were on medications, 49% (n=202) had good BP control. The average total cost of manpower during the 3-day health campaign was RM 5019.80 (USD 1059). The cost of detecting an individual with elevated BP was RM 12.27 (USD 2.59).
CONCLUSION: The prevalence of hypertension and unawareness is high. However, the average cost of manpower to detect an individual with elevated BP is low. Therefore, regular public health campaigns aiming to detect undiagnosed hypertension are recommended.

BACKGROUND: Information regarding the knowledge on the action to be taken during stroke and good recognition of stroke symptoms is mandatory in helping to plan out educational strategies to deliver health education to the community.
METHODS: This is a cross-sectional study of adults aged 18 and above attending a blood pressure screening program in community in conjunction with May Measurement Month 2017 in Malaysia. A structured self-administered questionnaire was given to the participants who gave verbal consent. Data analysis was done using SPSS v. 23 and multiple logistic regression was used to identify the determinants of knowledge on actions to be taken during stroke and recognition of stroke symptoms.
RESULTS: Out of 4096 respondents, 82.9-92.1% of them able to recognise the common stroke symptoms. and 74.2% of the study respondents will go to hospital within 4.5 h of stroke onset. According to binomial logistic regression analyses, adults aged 45 years old and above (OR 1.39 95%CI 1.01-1.92), being Malay (OR 1.74, 95% CI 1.27-2.40), being non-smokers (OR = 2.491, 95% CI: 1.64-3.78), hypertensives (OR: 1.57, 95% CI: 1.02-2.42)and diabetics (OR: 2.54, 95% CI:1.38-4.69) are determinants of right actions to be taken during stroke. Meanwhile, respondents aged 45 years old and older (OR = 1.68, 95% CI: 1.39-2.03), being Malay (OR = 1.49, 95% CI: 1.24-1.79), hypertensive (OR = 1.32, 95% CI: 1.04-1.66) and those who had a previous history of stroke (OR = 2.25, 95% CI: 1.01-5.00) are determinants of good recognition of stroke symptoms.
CONCLUSIONS: The overall knowledge of stroke in our study population was good. Older age, being Malay, non-smokers, hypertensives and diabetics are determinants of right actions to be taken during stroke. Meanwhile, older age, being Malay, hypertensive and those who had a previous history of stroke are determinants of good recognition of stroke symptoms.

The association between high salt intake and elevated blood pressure levels has been well-documented. However, studies on how effectively this knowledge translates into actionable practices, particularly across different ethnic groups, remain limited. This study aimed to evaluate the knowledge, attitudes, and practices (KAP) towards dietary salt intake across ethnicities and determine its association with hypertension. 5128 Malaysian adults recruited from a national blood pressure screening study completed questionnaires on demographics, and KAP related to dietary salt intake. There were 57.4% Malay, 23.5% Chinese, 10.4% Indian, and 8.7% individuals of other ethnic groups. Overall, more than 90% of the participants knew that a high salt intake causes serious health problems, but only around one-third knew the relationship between high salt intake and strokes and heart failure. Participants of different ethnic groups displayed significant differences in the KAP domains, where Indians generally exhibited better knowledge, attitudes, and reported better practices such as reading salt labels and using spices. Those who were unaware of the difference between salt and sodium and who reported not reading salt labels had higher odds of having elevated blood pressure. These findings demonstrate that while there is a suboptimal translation of salt knowledge into practice in Malaysia, with significant differences in KAP observed between ethnic groups, the potential of improving health outcomes by improving the clarity and awareness of salt labels is substantial. Tailored education promoting salt-label reading, minimizing processed foods intake and discretionary salt use should be ethnic-specific to better curb this escalating hypertension epidemic.

Hypertension continues to be the top global killer, contributing to over 10 million deaths annually. As prevalence and unawareness of hypertension remain high in Malaysia, this study was aimed to screen more individuals to identify those with undiagnosed hypertension. Respondents aged ≥18 years were recruited through opportunistic sampling at various screening sites including health clinics, hospitals, student health centres, universities, community halls, shopping malls, as well as through other health screening campaigns. Each respondent completed a questionnaire on socio-demographic, environmental, and lifestyle data. Anthropometric measurements as well as three blood pressure (BP) measurements were obtained from all participants. Hypertension was defined as a systolic BP ≥140 mmHg and/or diastolic BP ≥90 mmHg or taking antihypertensive medication. The total number of participants was 4866. The mean age of the participants was 39.8 (17.6) years with 61.1% female participants. Of the 4866 participants, 1405 (28.9%) had hypertension. The proportion of those aware of their hypertension status was 76.3% (1073/1405). The proportion of those with hypertension on medication was 71% (998/1405). Of those receiving antihypertensive treatment, 62.4% (623/998) had controlled BP. The proportion of hypertension in this study was 28.9%. The awareness rate of 76.3% compares favourably to a previously reported national level of 43.2%. Hence, BP screening programmes may be effective at increasing awareness and should be conducted annually.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. However there are still many individuals, particularly in many countries in Asia, who have poor BP control. In Malaysia, less than two-fifths have achieved BP control. We participated in BP screening in Malaysia in conjunction with the May Measurement Month 2017 (MMM17), a global initiative by the International Society of Hypertension (ISH) aimed at screening more individuals for earlier detection of hypertension. A nationwide screening of adults aged ≥18 was carried out through health campaigns at clinics, hospitals, during family day events, and charity runs from 1 April 2017 to 31 May 2017 in 42 centres. We used the detailed protocol provided by ISH for data collection. A total of 4116 individuals were screened during MMM17. After multiple imputation, 32.4% (n = 1317/4059) had hypertension. Out of this, 63.9% (842/1317) of those with hypertension were on treatment. Of individuals receiving antihypertensive medication with an imputed BP, 59.5% (n = 496/834) of them had controlled BP. MMM17 was the largest organized BP screening campaign undertaken by health professionals in Malaysia. This study identified that 32.4% of screened individuals had hypertension and 59.5% individuals with treated hypertension had achieved BP control.

This study aimed to examine the relationship of adherence with blood pressure (BP) control and its associated factors in hypertensive patients. This cross-sectional nationwide BP screening study was conducted in Malaysia from May to October 2018. Participants with self-declared hypertension completed the Hill-Bone Compliance to High Blood Pressure Therapy Scale (Hill-Bone CHBPTS) which assesses three important domains of patient behavior to hypertension management namely medication taking, appointment keeping and reduced salt intake. Lower scores indicate better compliance while higher scores indicate otherwise. Participant's body mass index and seated BP were measured based on standard measurement protocol. Determinants of adherence to treatment were analyzed using multiple linear regression. Out of 5167 screened subjects, 1705 were known hypertensives. Of these, 927 (54.4%) answered the Hill-Bone CHBPTS and were entered into analysis. The mean age was 59.0 ± 13.2 years, 55.6% were female and 42.2% were Malays. The mean Hill-Bone CHBPTS score was 20.4 ± 4.4 (range 14-47), and 52.1% had good adherence. The mean systolic BP and diastolic BP were 136.4 ± 17.9 and 80.6 ± 11.6 mmHg, respectively. BP was controlled in 58.3% of those with good adherence compared to 50.2% in those with poor adherence (p = .014). Based on multiple linear regression analysis, female gender (β = -0.72, 95% confidence interval [CI] -1.30, -0.15, p = .014), older age (β = -0.05, 95% CI -0.07, -0.03, p
