- Brief Summary
The transition to university from secondary school comes with many changes to living arrangements, dietary and alcohol intake, physical activity, and stress. The purpose of this study is to explore weight gain in new university students in the UK under the 'Freshman15' phenomenon. This phenomenon is an expression commonly used in the United States and Canada to describe a weight gain of 15 lbs (6.8 kg) in students who transition from secondary school to university life. The research will assess to investigate the impact of lifestyle factors that predict students' weight gain during their first year at the University of Aberdeen. The study specifically focuses on how these factors vary based on their living arrangement. Also, the change in lifestyle will be explored in relation to age-matched individuals not-attending university.
- Detailed Description
Detailed Description:
The study will be an observational study with four groups including three groups of university student and a group of age-matched volunteers living in the same city that are not attending university as a control:
1. University students living at home.
2. University students living in private accommodation.
3. University students living in the halls of residence.
4. Non-university participants living in Aberdeen.
Recruitment will take place over two academic years using flyers sent via email or distributed face-to-face among undergraduate first-year students at the University of Aberdeen (e.g., the Freshers Week), as well as in different public areas, such as supermarkets and shopping centres. If participants agree to participate in this study by signing the consent form, their involvement will last around eight months. This includes three research periods. One at the beginning of the academic year (late September/early October) and then a follow-up after three months (after the Christmas holidays in January), and at eight months (end of the academic year in May). Participants will be asked to come to a designated room at the University of Aberdeen. Each appointment will be in the morning (approx. 15 to 20 minutes for each visit). During each visit, participants will be provided with further details concerning the study and given time to ask questions.
Measures:
1. Anthropometric Measurements will be taken: Body Weight (BW), Body Mass Index (BMI), Sitting Height Ratio (SHR), Waist to Hip Ratio (WHR), Finger Ratio, Body Fat (BF%), and Weight-for- Age Growth Charts.
2. Dietary intake will be examined in two distinct ways. Firstly, self reported questionnaire. Secondly, participants will be asked to complete 3 \* 24-hour recalls to assess their consumption of ( protein (g), fat (g), carbohydrate (g), energy (kJ), alcohol (g), total sugars (g), non milk extrinsic sugars (g), fruit (g), vegetable (g), meat (g), processed meat (g), poultry (g), and fish (g) ). They will report two weekdays and one weekend day by using Intake24 online dietary recall system.
3. Physical activity will be examined in two ways. Firstly, self reported questionnaire. Secondly, participants will use an ActiGraph GT9X Link accelerometer (placed on the waist) to assess their physical activity (h), Activity intensity level (min), total awake duration (min), and total sleep duration (min) during weekdays and weekends. Participants will wear ActiGraph GT9X Link accelerometers for seven consecutive days except when taking a shower or swimming.
4. Stress: will be assessed via self reported questionnaire.
5. Socio-demographic characteristics: will be assessed via self reported questionnaire.
At the end of each visit, the researcher will explain how the accelerometer and 24-hour dietary recall will be employed.

- Primary Outcome Measures
Name Time Method Change in Body Weight (BW) Baseline at the beginning of the academic year, then a follow-up after three months, at eight months (end of the academic year ), and after one year. Weight (kilograms) will be measured using a Bioimpedance (Tanita MC-580 P).
Change in Body Mass Index (BMI) Baseline at the beginning of the academic year, then a follow-up after three months, at eight months (end of the academic year ), and after one year. Body Mass Index (BMI) will be measured height (Metres) using a Stadiometer and body weight (kilograms) using a Bioimpedance (Tanita MC-580 P). BMI (kg/m2) will be calculated by dividing weight by height squared.

Change in Bedtime on Weekdays using ActiGraph baseline at the beginning of the academic year, then a follow-up after three months, at eight months (end of the academic year ), and after one year. Bedtime will determine by identifying sudden periods of decreased activity levels which will dropped to zero and remained at that level for at least 5 consecutive epochs. To gain a metric variable, hours will count from 0 to 24, and hours after midnight will be counted as 25 (for 1:00), 26 (for 2:00), and so forth, which will then converted to decimal form; for instance, a bedtime of 21:30 will code as 9.50. The average bedtime will be analysed in hours and minutes (hh:mm) format.

Change in Physical Activity using questionnaire. baseline at the beginning of the academic year, then a follow-up after three months, at eight months (end of the academic year ), and after one year. Participants will be asked to complete a questionnaire that will evaluate physical activity. It includes six multiple-choice questions. I have categorical data with repeated measures, so I will use non parametric analysis with repeated measures to assess change from baseline to follow-up after three months and at eight months.
For example, physical activity will assessed by asked participants to report which best describes their level of physical activity (e.g., I am inactive and don't plan on starting in the next six months/ I am inactive but I'm thinking about starting in the next six months/ I do a bit of physical activity, but not a lot/ I have been doing physical activity for six months/ I have been doing physical activity for more than six months) etc.Change in Stress using questionnaire baseline at the beginning of the academic year, then a follow-up after three months, at eight months (end of the academic year ), and after one year. Stress will be assessed by employing a questionnaire which evaluates stress levels in the students. It includes four multiple-choice questions. I have categorical data with repeated measures, so I will use non parametric analysis with repeated measures to assess change from baseline to follow-up after three months and at eight months.
For example, the first question will asked participants to answer with (Yes /No) "Are you comfortable at their present level of stress?". The second question will, "How often do you feel stress?" participants provided with these options to choose from (e.g., (always/sometimes/rarely/never) etc..Change in lifestyle behaviours using questionnaire After one year at university lifestyle behaviours will be assessed by employing a questionnaire which evaluates changes in lifestyle behaviours. It includes eleven multiple-choice questions. I have categorical data with repeated measures, so I will use non parametric analysis with repeated measures to assess change after one year at university.
for example, the first question will asked participants to answer with (Yes /No) "Do you still live in the same place?".
Question 2. "Living Arrangement" (Home with family/Private accommodation/Halls of residence)3 Question 3. " Do you believe your eating habits have changed since the start of university?" (Yes/ No) etc.
