Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The data will collect from residential college of Universiti Teknologi Mara (UiTM) Puncak Alam which the candidates are among undergraduate student students from various programmes which are Health Sciences, Pharmacy, Accountancy, Education, Business and Management, Hotel and Tourism Management. The candidate must fulfil the inclusion and exclusion criteria before selected to be the sample of this research. The brief explanation given to the respondents by the researcher before they allow to fill the form. The researcher will explain to them regarding the information sheets, the procedure guidelines, consent form, the objective of this study and the duration of the procedure. The data are collected from the participants socio-demographic such as gender, age, and family history will be collected using information sheets before the intervention conduct. The information sheets consist of title, objectives, procedures, and confidentially of this study. A written consent form will be given to the participant to sign if the participant has agreed to participate in this study. The consent form explained to get the official agreement before conducting the research. After participants fill up the form, all the data collected will keep confidentially by keeping the participants’ names anonymously.

A day before the procedure, the participants need to fast 8 to 10 hours prior to experiment and not allow to drink or eat within the time given. The next day, before the procedure start, participants will need to do anthropometry which they need to weigh using weigh scale and measure height. Later, the researcher will calculate their Body Mass Index (BMI) to ensure the participants weight within normal range 18.4 to 24.9 kg/m² as stated in inclusion criteria to be part of the study. Those participants do not meet with BMI requirements will be excluded from this study. Next, participants need to take blood glucose level using glucometer for pre-prandial glucose reading as a baseline. Later, participants need to pick a paper that may label as A or B inside the box. The participants will be divided equally into two groups which are control group and intervention groups. The participants be in a group label as A and B and the breads will be distributed according to their labels. The researcher and participants will not know types of breads wrapped in A or B (double blinded). The breads will be packed by breads company X that will provide the packaging for the breads. Only the breads supplier will know the packaging A and B consists of which types of breads. The participants will be provided either whole grain breads or white breads. Intervention group is the low GI bread which refers to bread that has a lower impact on blood sugar levels compared to high-GI bread. Low GI made from wholegrain. Low GI bread refer as bread made using at least 80% of whole grains.


Participants are not allowed to drink water within 2 hours after consuming breads. Within 2 hours after eating the breads, post-prandial blood sugar reading will be taken. The results obtained will be collected and filled in the form. Participants will be expected to eat 2 slices (100g) of bread with no topping.

Statistical methods / analysis
IBM Statistical Package for Social Sciences Software (SPSS) version 29.0 will be used for data entering and analysing.

Sample size calculation.
The Sakpal formula (2010) will be used to calculate the required sample size:
Calculation of comparing two means.
Consider the drop out of 10% . Level of significance = 5%, Power = 80%, Type of test =two-sided.

where:
n = sample size required in each group,
µ1 = mean of post-prandial glucose level of white bread (control group).
µ2 = mean of post-prandial glucose level of wholegrain bread (intervention group).
µ1-µ2 = clinically significant difference = 0.5
ó = standard deviation = 33.2
Z a/2: This depends on level of significance = 1.96
Zß: This depends on power = 80% 0.84
Calculation based on previous study:

n= (1.96+0.84) ² x (2 ( 33.2 ) ² / (159.50 – 123.73) ²
n = (2.8) ²x (2204.48) / (35.77)²
n = 13. 50 (13 participants each group).
Since the sample is too small, therefore the popular rule of thumb will be used which sample size n= 30 for each group, control and intervention group. The total number of participants involves in this study n=60
