Because time management is closely related to employment status in adult population, this study also investigated the associations of time-of-day distribution of eating patterns with employment status.
Methods：This cross-sectional study used a national representative sample from the Nutrition and Health Survey in Taiwan(2005-2008).We analyzed data derived from 4508 eligible adult participants (≧19 years old),who had responses on the basic questionnaire and done one day 24-hour dietary recall. Reported time of intake was divided into six time periods (0500-0859h，0900-1259h，1300-1659h，1700-2059h，2200-0059h，0100-0459h). Time-of-day distribution of eating patterns were identified by cluster analysis on energy intakes of the six time periods. Their association with participants’ employment status was computed using multinomial logistic regression, adjusted for gender, age, education, health status, regional distribution and 24-hour dietary recall.
Results：Five different patterns were identified. The most common pattern was called “traditional pattern” (20.43%), which is comprised of energy intakes in three traditional meal times. The other patterns were：“traditional pattern plus afternoon snack” (14.30%)、“traditional pattern plus afternoon snack and evening snack” (17.73%)、“delayed or skipped breakfast pattern” (33.01%) and “delayed or skipped lunch pattern” (14.52%). Part-time job was associated with a higher odds ratio (OR=3.87, 95% CI=1.72-8.72) of being the “delayed or skipped lunch pattern” than full-time job, compared to being the “traditional pattern”. Unemployment was associated with a higher odds ratio of being the “delayed or skipped breakfast pattern” (OR=1.79, 95% CI=1.07-2.97) or the “delayed or skipped lunch pattern” (OR=2.04, 95% CI=1.02-4.08) than full-time job, compared to being the “traditional pattern”. Student was associated with a higher odds ratio of being the “traditional pattern plus afternoon snack” (OR=4.51, 95% CI=1.00-20.26) or the “delayed or skipped breakfast pattern” (OR=6.91, 95% CI=2.47-19.29) or the “delayed or skipped lunch pattern” (OR=15.94, 95% CI=4.82-52.72) than full-time job, compared to being the “traditional pattern”.
Conclusions：The majority of the adult population in Taiwan follows the “delayed or skipped breakfast pattern”. Our analysis shows that the employment status was associated with the time-of-day distribution of eating patterns.
