A Cross-Sectional Study of Gender Differences in Calorie Labeling Policy among Students: Dietary Habits, Nutritional...

Calorie labels may be the most important predictor of dietary choices among college students. The Saudi Food and Drug Authority (SFDA) has imposed calorie labels on the menus of restaurants and cafes. The current study looked at how the calorie labeling policy affects Saudi male and female students' dietary habits, nutritional knowledge, and awareness. The study included 802 students (360 males and 442 females) from Saudi Arabia's King Saud University, ranging between 18 and 35 years. Between December 2020 and October 2021, a cross-sectional, electronic, approved and validated survey was conducted to collect data on gender socio-demographic variables, food habits, and nutritional knowledge and awareness, in accordance with the food policy stated. The collected data were analyzed using descriptive statistical analysis. The Likert scale was used to determine the level of awareness and the food habit scores, and the Mann-Whitney U-test was used to determine the differences between the males and females. Spearman's correlation coefficient and simple regression analysis were performed to determine the association between the demographic factors and nutritional knowledge and the awareness of males and females. The results demonstrated that, with the exception of living situations, males and females differed significantly (p ≤ 0.01) in their socio-demographic characteristics. When asked about their food habits after the implementation of calorie labeling, the majority of respondents (>50%) gave negative responses, with a significant difference observed between maintaining body weight (p ≤ 0.05) and gaining weight (p ≤ 0.01). According to the Likert scale, there was a significant difference between males and females in terms of knowledge (p ≤ 0.01) and awareness (p ≤ 0.05). An average of 80.53% of males had very high knowledge (4.07) and 65.65% had medium level (3.24) awareness of calorie labeling, while 83.73% of females had very high knowledge (4.17) and 66.50% had medium level (3.32) awareness of calorie labeling. The socio-demographic and lifestyle variables were significantly and positively or negatively associated with calorie label utilization and varied between respondents, according to the Spearman correlation coefficients (r) and simple linear regression analysis. The number of factors that negatively impacted the males' knowledge and awareness was greater than that of the females. In conclusion, among college students, there were numerous gender differences in the demographic and social characteristics. The respondents' knowledge was insufficient, with females outperforming males.
