The immigrant population has grown considerably in South Korea since the early 1990s due to international marriages. Dietary changes in immigrants are an important issue, because they are related to health and disease patterns. This study was conducted to compare changes in dietary intake between baseline and follow-up periods.

Two hundreds thirty three Vietnamese female married immigrants. Baseline data were collected during 2006-2009, and the follow-up data were collected during 2008 and 2010. Food consumption was assessed using a 1-day 24-hour recall.

The amount of the total food consumed ( P < 0.001) including that of cereals ( P = 0.004), vegetables ( P = 0.003), and fruits ( P = 0.002) decreased at follow-up compared to that at baseline, whereas consumption of milk and dairy products increased ( P = 0.004). Accordingly, the overall energy and nutrient intake decreased at follow-up, including carbohydrates ( P = 0.012), protein ( P = 0.021), fiber ( P = 0.008), iron ( P = 0.009), zinc ( P = 0.006), and folate ( P = 0.002). Among various anthropometric and biochemical variables, mean skeletal muscle mass decreased ( P = 0.012), plasma high density lipoprotein-cholesterol increased, ( P = 0.020) and high sensitivity C-reactive protein decreased at follow-up ( P < 0.001).

A long-term follow-up study is needed to investigate the association between changes in food and nutrient intake and anthropometric and biochemical variables in these Vietnamese female marriage immigrants.
