OBJECTIVES: To create a translation of the Chrononutrition Profile Questionnaire (CPQ), test its validity and reliability, and determine the general chrononutrition behaviors among Malaysian young adults.
METHODS: The Malay-CPQ was distributed to respondents through online platforms (n = 110), and data analyses were performed. The data were analyzed for their validity using content validity index (CVI) and face validity index (FVI), whereas intraclass correlation coefficient (ICC) was used to determine test-retest reliability.
RESULTS: Our results showed both CVI and FVI of Malay-CPQ were 1, indicating excellent content translation, while the ICC values ranged from moderate to good (0.50-0.90). The Cronbach α values for all items ranged from moderate to good (0.50-0.90), and the Bland-Altman analysis showed a P value >0.05, indicating agreement of the item between repeated measurements. The chrononutrition behaviors among Malaysian young adults presented fair to good scores for all behavior patterns: eating window, breakfast skipping, evening eating, night eating, and largest meal, except evening latency, being mostly at the poor score (>80% responses).
CONCLUSIONS: The Malay-CPQ is a valid and reliable tool to assess the Malaysian chrononutrition profile. However, further testing on Malay-CPQ should be conducted in a different setting in Malaysia for cross-validation studies.
METHODS: This cross-sectional study was conducted on 409 college students aged above 18 in Malaysia. The chrononutrition behavior was assessed using the validated Chrononutrition Profile Questionnaire (CP-Q). The questionnaire was distributed using an online platform. Participants self-reported their body weight and height, and the Body Mass Index (BMI) was computed. Data were analyzed using the SPSS software.
RESULTS: A total of 409 participants were recruited, with a mean age of 21.5 ± 2.2 years. The prevalence of underweight, normal, and overweight was 24.7, 49.4, and 25.9%, respectively. The chrononutrition behavior revealed that participants ate breakfast about four times/week (mean 4.27 ± 2.43 days), and only 135 (33.0%) consumed breakfast daily. The largest meal consumed was during lunch (75.8%), and the mean of snacking after the last meal was 3.23 ± 2.01 days. The prevalence of night eating was low, and most participants (70.9) did not wake up at night to eat. The frequency, however, was significantly higher in the underweight group compared to the normal weight group (p < 0.05). We observed a significant association between BMI and eating window, evening latency, evening eating, and night eating. It was found that the underweight had a poor eating window (p < 0.01), poor evening latency (p < 0.01), poor evening eating (p < 0.01), and poor night eating (p < 0.05) compared to those with normal and overweight BMI groups. In contrast to predictions, poor chrononutrition behavior was more likely to predict being underweight compared to normal (p < 0.05).
CONCLUSION: Underweight young adults are more likely to have poor chrononutrition behavior. The results of the present study suggest that future nutrition education should also focus on the chrononutrition behavior of college students.
