About this study

Official title: Efficacy of Counselling for the Prevention of Hypertension Among Slum Dwellers in Dhaka City, Bangladesh

This study aims to evaluate the effectiveness of counseling interventions in promoting positive changes in hypertension markers among adult slum dwellers. The intervention is designed to address modifiable risk factors, such as physical inactivity, obesity, unhealthy dietary practices, tobacco and harmful uses of alcohol within a resource-limited community setting. The main question it aims to answer is:

  • Is counseling a more effective intervention for the prevention of hypertension among adult slum dwellers in Dhaka city compared to other interventions?

Participants will:

  • provide data related to tobacco use, physical activity, and dietary intake.
  • provide a sample for blood pressure measurements. Will receive the WHO Brief Counselling intervention through 20 personalised sessions (each lasting approximately 20 minutes), focusing on lifestyle modifications, including physical activity promotion, balanced nutrition, and hypertension awareness.
Read the detailed description

This study aims to provide valuable insights into the effectiveness of counseling interventions in improving hypertension-related health outcomes among vulnerable urban populations. By focusing on modifiable risk factors, such as physical activity, dietary behavior, and tobacco use, the study will assess the potential of personalized counseling to reduce obesity, improve lipid profiles, and lower blood pressure. The intervention group will receive leaflet and counseling; and the control group will receive a leaflet only. After randomization, we will perform a baseline assessment. The participants will be allocated using stratified randomization. Allocation coverup will be ensured by performing allocation after completing all baseline assessments. A researcher who will not directly be involved with study delivery will allocate participants in a 1:1 ratio, generating a random sequence.

For both the primary and secondary outcomes, an intent-to-treat (ITT) design will be employed to ensure the robustness of the findings by including all participants, regardless of whether they complete the study or drop out. To address the potential impact of missing data due to dropout, participants will still be invited back for final assessment evaluations, minimizing bias in outcome measurement.

Through rigorous monitoring of primary and secondary outcomes in a double-blinded randomized controlled trial, the findings are expected to contribute to evidence-based public health interventions tailored for slum communities in Dhaka. These insights will guide future programs aimed at reducing the burden of hypertension and associated cardiovascular risks. The study will also highlight the importance of community-level preventive strategies in addressing chronic diseases where access to healthcare is limited. Ultimately, the research can inform scalable public health initiatives, advancing efforts toward equitable healthcare solutions in urban low-income settings

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. BMI classification (kg/m²)

    Body mass index (BMI) will be calculated as weight in kilograms divided by height in meters squared (kg/m²). The participants will be considered as obese and over-weight when BMI ≥ 30kg/m2 and 25-29.9 kg/m2, respectively

    Measured: From enrollment until 18 months

  2. Waist circumference (cm)

    Central obesity was categorized according to the cut-off value specified by the international Diabetes Federation--- waist circumference 90 cm for men and 80 cm for women or waist-hip ratio>0.90 for men and >0.85 for women.

    Measured: From enrollment until 18 months

  3. Waist-to-hip ratio

    Waist-to-hip ratio will be calculated as the ratio of waist circumference to hip circumference. Central obesity will be defined as a ratio >0.90 in men and >0.85 in women.

    Measured: From enrollment until 18 months

  4. Tobacco use in the past 30 days

    Those who have the past 30 days history of smoking or use of smokeless tobacco will be considered as a current tobacco user.

    Measured: From enrollment until 18 months

  5. Physical activity level (MET-minutes/week)

    As per the WHO STEPS protocol, we were converted all work-related physical activities in metabolic equivalent of task in minutes per day (MET-minute) as follows:

    1 minute in sedentary position = 1 MET-minute

    1 minute in a moderate physical activity = 4 MET-minutes

    1 minute in a vigorous physical activity = 8 MET-minutes

    All MET-minutes were then added together to get the cumulative MET-minutes. As per the cumulative MET-minutes, participants were categorized as less, moderately, and highly active:

    • 600 MET-minutes per week = less active
    • 600-3000 MET-minutes per week = moderately active ≥ 3000 MET-minutes per week = highly active

    The rest of the respondents, those didn't not meet even moderate activities, they were categorized as low activity

    Measured: From enrollment until 18 months

  6. Inadequate fruit and/or vegetables intake (servings)

    WHO recommendation of fruit and/or vegetable intake <5 servings per day was considered as an inadequate intake. Participants will be asked about the number of days they used to eat fruit and vegetables in a week and the number of servings on those days they eat these. One standard serving size equal to 80 grams.

    Measured: From enrollment until 18 months

  7. Dietary salt intake

    The added salt consumption will be defined as taking dietary salt during eating a meal.

    Measured: From enrollment until 18 months

Secondary outcomes (10)
  1. Systolic Blood pressure (mmHg)

    The blood pressure of the respondents will be measured following WHO guideline for blood pressure measurement using WHO-certified automated blood pressure monitor namely OMRON model HEM-7121 made in Japan. Hypertension will be defined as SBP ≥140 mmHg or if the participant is on antihypertensive treatment.

    Measured: From enrollment until 18 months

  2. Diastolic blood pressure (mmHg)

    The participants will be considered hypertensive when the systolic blood pressure reading was ≥140 mmHg and/or the diastolic blood pressure reading was ≥ 90 mmHg or known case hypertensive or on antihypertensive medication. Raised blood pressure means SBP: ≥ 120 mmHg and /or DBP: ≥ 80 mmHg

    Measured: From enrollment until 18 months

  3. Heart rate (beats per minute)

    Heart rate refers to the number of times the heart beats per minute (bpm). In this study, heart rate will be measured using a validated automated device (OMRON model HEM-7121) following the standard protocols recommended by the World Health Organization. Participants will be instructed to rest for at least five minutes before the measurement to ensure accuracy. Heart rate readings will be taken at baseline and follow-up intervals to track any significant changes over time, with abnormal heart rates defined as below 60 bpm (bradycardia) or above 100 bpm (tachycardia) in accordance with clinical guidelines.

    Measured: From enrollment until 18 months

  4. Lipid profile (mg/dL)

    Serum total cholesterol, triglycerides and HDL-cholesterol will be measured by end-point method using Backman Coulter AU-480 automated Biochemistry analyzer. Serum LDL-cholesterol will be calculated using Friedewald formula.

    Dyslipidemia was defined as Total Cholesterol ≥ 200 mg/dl, or Triglycerides ≥150 mg/dl, or Low-density lipoprotein cholesterol (LDL-C) ≥ 130 mg/dl, or HDL-C < 40 mg/dl (for men) and High-density lipoprotein cholesterol (HDL-C) < 50 (for women)

    Measured: From enrollment until 18 months

  5. Fasting blood glucose (mg/dL)

    Fasting blood sugar levels will be measured from venous samples following an 8-hour fast using the Turbidimetric Immunoinhibition methods using Backman Coulter AU-480.

    Measured: From enrollment until 18 months

  6. Diagnosis of Type 2 Diabetes Mellitus

    Type 2 diabetes mellitus will be diagnosed if fasting blood glucose is ≥126 mg/dL or if the participant is on antidiabetic medication, following WHO criteria.

    Measured: From enrollment until 18 months

  7. High-sensitivity C-reactive protein (hs-CRP) (mg/L)

    Hs-CRP will be measured using turbidimetric immunoassay methods with a Beckman Coulter AU-480 automated biochemistry analyzer. Blood samples will be collected from participants after fasting, and Hs-CRP levels will be expressed in milligrams per liter (mg/L). Following clinical standards, values below 1 mg/L indicate low cardiovascular risk, 1-3 mg/L represent moderate risk, and above 3 mg/L indicate high cardiovascular risk

    Measured: From enrollment until 18 months

  8. Urine creatinine test (mg/dL)

    Following instruction on proper urine preservation, participants were given a 15-20 ml sterile labeled container to collect urine for urine specimens, which were to be stored overnight at room temperature before being collected the following morning. The creatinine level was estimated using the Jaffy method and the Backman Coulter AU-480 automated Biochemistry analyzer was used to measure serum creatinine.

    Measured: From enrollment until 18 months

  9. Urinary sodium (Na+) and potassium (K+) estimation (mmol/L)

    In this investigation, we employed the Tanaka equation to estimate 24-hour urine Na+, K+, and Na+/K+ ratio. The equation used Japanese data items from the INTERSALT project, which was carried out using a highly standardized technique, to build this equation to estimate 24-hour urine Na+ and K+ excretion. By contrasting 24-hour urine samples with spot urine from the same participants, they were able to create this equation. Additional data utilized to create the equation included the respondents' age, sex, height, weight, and creatinine levels. This was then used to get the 24-hour sodium intake, which was then divided by 17.1 as a conversion factor to determine the predicted salt intake in grams. Using the Backman Coulter AU-480 automated biochemistry analyzer, the ISE method will be used to measure the amount of sodium (Na+) in the urine.

    Measured: From enrollment until 18 months

  10. 10-year cardiovascular disease (CVD) risk prediction

    CVD risk will be estimated using WHO/ISH risk prediction charts (version 2023), incorporating factors like age, sex, blood pressure, smoking status, diabetes, and total cholesterol. Risk will be categorized as very low risk <5%, low risk 5%-<10%, moderate risk 10%-<20%, high risk 20%-<30% and very high risk ≥30%

    Measured: From enrollment until 18 months
