Summary:
To assess the effectiveness of instant message-delivered personalised lifestyle modification (LSM) intervention for pre-hypertension (pre-HTN) management among community dwelling Chinese adults.

Primary Outcome Measures: 24hr-systolic and diastolic BP, The BP will be measured by 24hr-ambulatory BP monitoring., 6 months
Secondary Outcome Measures: DASH diet adherence (Self-reported quesionnaire), A self-reported questionnaire will be utilized to assess adherence to the DASH diet, based on the portions consumed in the previous week as reported by the participants., 6 months|Salt-intake literacy (Chinese Health Literacy Scale for Low Salt Consumption - Hong Kong, CHLSALT-HK), The 49-item CHLSalt-HK had a possible score range of 0 to 98, with a higher score indicating higher health literacy related to salt intake., 6 months|Physical activity (International Physical Activity Questionnaire - Short Form, IPAQ-SF), The IPAQ-SF is designed to measure the level of physical activity among adults over a week, including vigorous and moderate activities, walking, and sitting time. Scoring is based on the type, frequency, and duration of activities, converting activity levels into Metabolic Equivalent Task (MET) minutes per week to assess overall physical activity. Vigorous activities are calculated at 8 METs per minute, moderate activities at 4 METs, and walking at 3.3 METs. The total activity score is the sum of MET minutes per week for all activities, categorizing participants into low, moderate, or high physical activity levels based on their total score., 6 months|Body Mass Index (BMI), BMI is calculated by dividing an individual's weight in kilograms by their height in meters squared. Higher BMI can indicate higher body fatness., 6 months|Psychological well-being (Patient Health Questionnaire, PHQ-4), A 4-item scale with score ranging from 0 to 12, higher scores indicate higher severity of mental health problems., 6 months|Quality of life (EuroQol 5-dimension 5-level questionnaire, EQ-5D-5L), The EQ-5D-5L assesses five health dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, each rated on five levels of severity, with scores ranging from -0.864 to 1, where higher scores indicate better quality of life. Additionally, it includes a visual analogue scale (VAS), ranging from 0 (the worst health imaginable) to 100 (the best health imaginable)., 6 months|Feedback on instant message-delivered personalised lifestyle modification intervention, Feedback on the blood pressure management program will be collected, focusing on various aspects such as perceived usefulness and willingness to recommend the program. Each aspect will be evaluated using a 5-point Likert scale, where higher scores indicate more positive evaluations., 6 months
