Introduction: Many details about adolescent women's lifestyles and masked obesity have not been clarified in prior research. Thus, we conducted an exploratory survey on the lifestyle and masked obesity in female college students.
Methods: From September to October in 2012, we investigated 85 female students aged 18-23 years in two colleges in the Kanto area and cross-sectionally investigated the differences in lifestyles between subjects with masked obesity [Body Mass Index (BMI) <25 kg/m2 and Body Fat Percentage ≥30%] and those with standard proportions (18.5≤BMI<25 kg/m2 and Body Fat Percentage=20-25%). Their body composition was measured using InBody430, and their lifestyles were investigated using a self-administered questionnaire.
Results: Of them, there were 6 subjects (7.1%) with standard proportions and 25 subjects (29.4%) with masked obesity; 44.6% of the 56 subjects with standard weights had masked obesity. Differences were observed in their food intake frequency; the subjects with masked obesity consumed a smaller daily intake of green and yellow vegetables (p<.001) and light-colored vegetables (p=.008), and more frequently consumed mayonnaise (p=.003) and fried foods (p=.018) than those with standard proportions.
Conclusion: Masked obesity may increase the probability of having unhealthy dietary habits. It may be necessary for females with standard weights to receive dietary advice, and to have their body fat percentage regularly measured.
