This study investigated the effects of an individual’s economic status and frequency of eating with adults and at-home meal preparation while in junior high school on his/her vegetable intake frequency in adulthood. We selected men and women aged 20-49 years via an internet survey. The survey comprised data on participants’ current height and weight; weight at 20 years of age; economic status, frequency of eating with adults, and frequency of at-home meal preparation while in junior high school; and current vegetable intake frequency. The current vegetable intake frequency was significantly higher among individuals who were wealthier while in junior high school than among their poorer counterparts (OR: 2.56 [95% CI: 1.53-4.31], p=0.0004, p for trend=0.0003). Individuals who ate breakfast with an adult and those who prepared meals at home more frequently when in junior high school had a significantly higher current vegetable intake frequency ([eating with adults] OR: 1.89 [95% CI: 1.31-2.71], p=0.001, p for trend=0.001 [at-home meal preparation] OR: 4.71 [95% CI: 2.69-8.24], p<0.0001, p for trend <0.0001). Thus, eating breakfast with adults and at-home meal preparation during junior high school was associated with higher current vegetable intake frequency, independent of the economic status during junior high school.
