10. Summary of thesis results:
A cross-sectional quantitative study on “The relationship between eating habits, body satisfaction and happiness in adults”, focusing on understanding the current situation and clarifying the relationship between them. A survey was conducted from April to May 2024 using a convenient sampling method, collecting 239 adults (from 18 to 45) with an average age of 24.14, SD = 5.39, of which 76.2% were female and mainly lived in urban areas of Hanoi, Thai Binh, Hung Yen provinces. Survey participants answered a questionnaire consisting of two parts. Part 1: Includes demographic information (including gender, year of birth, weight and height index, area of residence, economic situation, current occupation, family type, education level, etc.). Part 2: includes research tools: Eating Habits Scale: Importance of food for health, frequency of meals at the place of residence, frequency of consumption of food groups and drinks, emotional eating habits, daily meal times (number of meals on time during the day). Body Satisfaction Scale in the total scale Body Image Scale - Appearance MBSRQ-AS (Multidimensional Body-Self Relations Questionnaire- Appearance Scales) (Cash, 2000) has been adapted in Vietnam by authors Truong Thi Khanh Ha, Phan Thi Thao (2021) including 25 items; Mental Health Continuum - Short Form Scale; Keyes (1998, 2002)), abbreviated as MHC-SF has been adapted in Vietnam by authors Truong Thi Khanh Ha (2015) including 14 items. The results of the study show that: The eating habits of adults are relatively healthy, reflected in eating on time, consuming lots of vegetables, fruits and filtered water, and limiting carbonated drinks and alcohol. Adults have relatively good body satisfaction and happiness. There are differences between groups: Women care more about their appearance and tend to eat emotionally more than men. The group over 25 years old has healthier eating habits and feels happier than the group 18-24 years old. The higher the income, the healthier the eating habits and the higher the level of satisfaction with life. There is a statistically significant relationship between eating habits, body satisfaction and happiness in adults. In the predictive relationship: Eating habits (breakfast, water) explain 13% of the variation in happiness. Body satisfaction explains 27.5% of the variation in happiness. Body satisfaction acted as a mediator in the relationship between eating habits and perceived happiness. Economic status evaluation and exercise activity acted as moderators in the relationship between eating habits and body satisfaction and perceived happiness.

10. Summary of the findings of the thesis:
A cross-sectional quantitative study titled “The Relationship Between Eating Habits, Body Satisfaction, and Subjective Well-Being in Adults” focused on investigating the current situation and clarifying the relationships among these variables. The survey, conducted from April to May 2024, employed a convenience sampling method and collected data from 239 adults aged 18 to 45 (mean age = 24.14, SD = 5.39). Among the participants, 76.2% were female, and most resided in urban areas of Hanoi, Thai Binh, and Hung Yen provinces. Respondents answered a questionnaire divided into two sections. Section 1 included demographic information such as gender, year of birth, weight and height indices, area of residence, economic status, current occupation, family type, and educational level. Section 2 confers of research instruments: the Eating Habits Scale, which measures the importance of food for health, meal frequency at home, consumption frequency of food and beverages, emotional eating habits, and daily eating schedule (number of on-time meals per day); the Body Satisfaction Scale, adapted from the Multidimensional Body-Self Relations Questionnaire - Appearance Scales (MBSRQ-AS) (Cash, 2000) by Truong Thi Khanh Ha and Phan Thi Thao (2021), with 25 items; and the Subjective Well-Being Scale, adapted from the Mental Health Continuum – Short Form (MHC-SF) by Keyes (1998, 2002) by Truong Thi Khanh Ha (2015), with 14 items. The findings indicate that adults demonstrate relatively healthy eating habits, such as regular meals, high consumption of vegetables and water, and limited intake of carbonated drinks and alcohol. They reported moderate levels of body satisfaction and subjective well-being. Females were found to care more about appearance and showed a higher tendency for emotional eating compared to males. Adults over 25 demonstrate healthier eating habits and greater well-being than those aged 18–24, while higher income is linked to healthier eating habits and greater life satisfaction. A significant statistical relationship was observed between eating habits, body satisfaction, and subjective well-being. In predictive relationships, eating habits (eg, breakfast and water consumption) accounted for 13% of the variance in subjective well-being, while body satisfaction explained 27.5% of the variance. Body satisfaction played a mediating role between eating habits and subjective well-being. Additionally, economic status and physical exercise served as moderators in the relationships between eating habits, body satisfaction, and subjective well-being.
