Inclusion criteria

  • All patients aged 60 years and older who had been diagnosed with hypertension for more than 3 months at the time of the study were eligible for inclusion.

Exclusion criteria

  • People who are not able to answer interviews or have mental illnesses.

Treatment and study plan

Adherence

Behavioral

Patients received interventions as follow:

  • The health education syllabus included 4 chapters: (1) introduction to hypertension, (2) complications of high blood pressure, (3) lifestyle management, and (4) SCORE - European High-Risk Chart
  • Home health education by Community Health Workers every month for 6 months

Primary outcomes

  1. Change Medication adherence

    Time frame: Patients were assessed Medication adherence at 3 time points: baseline (at the start of the study), 7 months after baseline, and 13 months after baseline

    Medication adherence was assessed using The 8-item Morisky Medication Adherence Scale (MMAS-8). The scale is based on the patients' self-response and consists of eight questions, seven items with yes or no response, and one item with a 5-point Likert scale response option. The total score ranges from 1 to 8, the patient whose adherence score was six or more is considered adherent.

Secondary outcomes

  1. Change Follow-up compliance

    Time frame: Patients were assessed Follow-up compliance at 3 time points: baseline (at the start of the study), 7 months after baseline, and 13 months after baseline

    patients are considered Follow-up compliance when they have had a follow-up examination for hypertension in the past 3 months, according to the doctor's appointment, or early/delayed within 3 days

  2. Change Compliance with reducing salt intake

    Time frame: Patients were assessed Compliance with reducing salt intake at 3 time points: baseline (at the start of the study), 7 months after baseline, and 13 months after baseline

    patients are said to comply with salt reduction when using < 5g salt/day (corresponding to < 1.9g Na/day). Daily sodium intake was calculated based on the Food Frequency Questionnaire (FFQ) on foods high in salt (preserved meat, salt, fish sauce, soy sauce, ketchup) according to the formula [portion size in grams] x [reported consumption frequency (converted to times per day)] x [nutrient per gram]

  3. Change Physical activity compliance

    Time frame: Patients were assessed Physical activity compliance at 3 time points: baseline (at the start of the study), 7 months after baseline, and 13 months after baseline

    Physical activity compliance assessed by The International Physical Activity Questionnaire - Short Form (IPAQ-SF). The IPAQ-SF includes 4 questions, collects physical activity information for the previous 7 days regarding vigorous and moderate activity, walking and sedentary behaviors, units in MET-minutes/week. Patients were considered compliant with moderate and high levels of physical activity according to the IPAQ-SF assessment guidelines.

  4. Change Smoking compliance

    Time frame: Patients were assessed Smoking compliance at 3 time points: baseline (at the start of the study), 7 months after baseline, and 13 months after baseline

    patients are considered Smoking compliance when they currently do not smoke or completely quit smoking (including e-cigarettes)

  5. Change Compliance with alcohol consumption

    Time frame: Patients were assessed Compliance with alcohol consumption at 3 time points: baseline (at the start of the study), 7 months after baseline, and 13 months after baseline

    patients are considered Compliance with alcohol consumption when minimizing alcohol consumption, if drinking, the amount should be ≤ 2 standard drinks/day (men) or ≤ 1 standard drinks/day (women), and the total must be ≤ 10 standard drinks/week (men) or ≤ 5 standard drinks/week (women)
