About this study
Official title: The Effectiveness of Intermittent Fasting Towards Elevated Blood Pressure Among Civil Servants in Aceh
To date, the prevalence of Hypertension (HPT) is getting increase worldwide. This situation is contributed mostly by the Lower-Income Countries (LIC) and Lower-Middle-Income Countries (LMICs) include Asians. Elevated Blood Pressure (EBP) in the early phase is often unrealized before developing to HPT, leading to several diseases in terms of cardiovascular diseases (CVDs). In preventing EBP, the European Society of Cardiology in 2017 classifies blood pressure into three groups; normal, pre-hypertension, and hypertensive crisis. People in the normal phase with the high-normal line are classified into EBP. If this group is determined and controlled, they will further keep in normal blood pressure. Contrarily, they are experiencing the next phase of HPT.
Like other Asian countries, Indonesia was experiencing an extreme prevalence of HPT, and Aceh, which is one of the provinces in Indonesia has a very high prevalence of HPT as well (20% increment from 2013-2018), is estimated to equal to the EBP prevalence. Despite many promotive and preventive interventions confirmed to decrease HPT, early screening has been convinced to recover the HPT in Indonesia. However, the HPT prevalence was examined steadily increasing. Intermittent fasting (IF) is recognized as a new method in decreasing metabolic factors based on several types of research currently. Therefore, the investigators are studying the effectiveness of intermittent fasting on people with EBP. Conducting healthy lifestyle intervention that is inexpensive, doable, and easily accessible, would be a new method for controlling EBP.
Read the detailed description
This trial aims to evaluate the effectiveness of three months intermittent fasting intervention followed by three months maintenance phase in stabilizing blood pressure among the EBP group with the high-normal signal. This trial will conducts in Aceh, Indonesia.
Trial procedure
- In the beginning, the researcher chooses the allocation group for either intervention or control group based on the potential number of workers from each department. Based on that, it was decided that the intervention group is the Governor's office, and the Aceh Besar regency secretariat is the control group.
- Letters of permission are submitted to both departments and continued by blood pressure screening once it is approved. Hence, the enumerators will screen all the workers. Each eligible participant (EBP 130-139/85-89 mm Hg and BMI ³ 25 kilograms/m2) will be invited to join blood pressure plus nutrition class on the day after, and fulfill the baseline characteristic questionnaire once they sign the informed consent. During the class, the researcher will describe the study procedure, study objective, process, monitoring, follow-up, methodology, risk and benefit, confidentiality, anonymity, and withdrawal from the study in both groups with the different context of intervention. Because of the covid-19 pandemic, all participants are allocated in a few small groups during baseline training.
- The participants will join complete anthropometric measurements and fulfill questions in the STEP instrument and GPAQ instrument. Four enumerators will assist the participants; however, they will be blinded to intervention assignment.
- The intervention group will undergo two fasting days and five ad libitum days during the intervention phase and continued to the maintenance phase. Otherwise, the control group will have a usual diet before the trial. Furthermore, both groups will have current exercise.
- Calculation of the actual sample size to detect effect size in the primary and secondary objectives of the project has been conducted. Sample selection techniques will be described further in the published paper.
- A mixed linear model will be applied to count the intervention effects (blood pressure, body weight, body mass index, waist circumference, and calorie intake), while a generalized estimating equation (GEE) will be used as well for categorical outcomes. Characteristics at baseline will be summarised by each arm using numbers and percentages, means and standard deviations or medians, and inter-quartile ranges where applicable.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Intermittent fastingBehavioural
The intervention group is required to perform intermittent fasting for two days. The intermittent fasting method for this group will mimic the Sunnah Muslim fasting; they are allowed to consume food and calorie water without restriction in between dusk and dawn. During the five ad libitum days, they are allowed to have a variety of foods and drinks. Subjects will be informed about healthy food choices; choosing low-fat meat and dairy options, increasing fruit and vegetable intake.
No interventionOther
The control group will receive education training at the baseline as well, regarding blood pressure and nutrition. They will have usual exercise prior to the intervention. Furthermore, the group will have equal health education through health promotion leaflets which have been issued by the ministry of health.
| Study group | Role | What they receive |
|---|---|---|
| intervention group | Experimental | two fasting days and five ad-libitum days followed by usual exercise. Receives: Behavioral: Intermittent fasting |
| Control group | Sham comparator | Usual diet and usual exercise prior to the intervention. Receives: Other: No intervention |

The primary outcome is the main question the study is designed to answer.
Blood pressure
Change from baseline systolic blood pressure and diastolic blood pressure at 12 weeks and 24 weeks (6 months) in participants with elevated blood pressure and BMI above is equal to 25 kilogram/m2.
The blood pressure is measured by Omron sphygmomanometer (Omron HEM 7130 LP, Kyoto, Japan).
Measured: Baseline, 12 weeks and 24 weeks
Secondary outcomes (4)
Body weight
Change from baseline body weight at 12 weeks and 24 weeks (6 months) in participants with elevated blood pressure and BMI above is equal to 25 kilogram/m2.
The body weight is measured by weighing scale (Oserio Body fat monitor, Guozhong, Taiwan)
Measured: Baseline, 12 weeks and 24 weeks
Body mass index
Change from baseline BMI at 12 weeks and 24 weeks (6 months) in participants with elevated blood pressure and BMI above is equal to 25 kilogram/m2.
The BMI is measured by weighing scale (Oserio Body fat monitor, Guozhong, Taiwan) and Stadiometer (Saga, Indonesia)
Measured: Baseline, 12 weeks and 24 weeks
Waist circumference
Change from baseline waist circumference at 12 weeks and 24 weeks (6 months) in participants with elevated blood pressure and BMI above is equal to 25 kilogram/m2.
The waist circumference is measured by tape line (China)
Measured: Baseline, 12 weeks and 24 weeks
Calorie intake
Change from baseline calorie intake at 12 weeks and 24 weeks (6 months) in participants with elevated blood pressure and BMI above is equal to 25 kilogram/m2.
The calorie intake is measured by three days food record form.
Measured: Baseline, 12 weeks and 24 weeks

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Blood pressure (time frame: Baseline, 12 weeks and 24 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04953650, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2023; AzTrials last refreshed its copy on 30 Oct 2026.
