increasing1 and gender influence general blood test and BMI values, and menopause is known to influence plasma lipid concentrations in both sexes 2. Individual regions have particular lifestyles that are reflected in the incidence of lifestyle related disease 3 and lifestyle is thought to affect the results of annual health screenings, especially those for BMI, serum glucose and lipid profiles. Obesity has become a major health concern in industrialized societies and it is a major risk factor 5 of metabolic disorders like metabolic syndrome (MetS), which are considered a world-wide public health problem for the 21st century 4. One of the features of MetS is the age-related, sex-related, region-related and lifestyle-specific differences in its incidence6−8. However, it may be worth mentioning, in passing, that some studies have reported an association with cognitive physical and/ or mental impairments and medications for older patients with MetS 9. Therefore, a therapeutic approach for elderly adults with MetS remains to be established and in individual regions, recognizing differences in the health check-up measurements according to age or sex will be very important for determining the timing and methods of therapeutic interventions for diseases, especially obesity. In this study the main objective was to investigate general tendencies in ageand sex-related differences in BMI and blood test values in Japan.
