To investigate the effect of several factors on serum lipids in maternal and infants umbilical cord blood, 111 cases of newborn infants and women delivered of a child who had delivered at hospital located in Chung-Ju city from Feb. 1, 1996 to Aug. 31, 1996 were studied. The gestational ages of cases were 37 to 42 weeks and the average maternal ages were 28.1$\pm$4.25 years old without any other medical or obstetric problems. No relationships between maternal consumption of coffee and maternal serum lipid levels were observed. However, serum total cholesterol and LDL-cholesterol levels in infants'umbilical cord were significantly increased in proportion to increasing maternal consumption of coffee. The other factors such as alcohol drinking habits and residency affected maternal serum lipid levels and not serum lipid levels in infants' umbilical cord. Delivery frequency showed very little or no effects on serum lipid levels in both maternal blood and infant's umbilical cord blood. In conclusion, maternal consumption of coffee significantly correlated with increasement of serum lipid levels in infants'umbilical cord.

Purpose: Coffee is the most frequently consumed food item in South Korea after rice and cabbage. Coffee contains various substances, including caffeine, cafestol, kahweol, chlorogenic acid, and many other known and unknown ingredients with some health benefits. Especially, cumulative evidence has shown that regular coffee use is associated with lower risk of type 2 diabetes, although limited and inconsistent data are available regarding metabolic syndrome. Methods: This study reviewed all available scientific and epidemiologic evidence on coffee consumption, metabolic syndrome, and the association between them. Most epidemiologic research regarding this association was of a cross-sectional design, and a few case-control and cohort studies were available. We conducted meta-analysis with 11 observational studies investigated in Europe, America, and Asia. Summary odds ratios (OR) were calculated using a random-effects model. Results: The overall OR of metabolic syndrome was 0.90 (95% Confidence Interval (CI), 0.81-0.99) for the highest category of coffee intake compared with the lowest intake category. These associations were stronger in populations of US and Europe (OR 0.84, 95% CI 0.76-0.94), whereas no association was observed in the Asian population (OR 1.00, 95% CI 0.81-1.23). Conclusion: The review results indicate that frequent coffee consumption may be beneficial to metabolic syndrome, but the association between coffee consumption and metabolic syndrome may differ by nations or continents.

This paper estimated how demographic characteristics, food selection preferences, daily physical activities, and food purchasing patterns of consumers affect the consumer choice to buy coffee and tea by analyzing the Consumer Panel data in 2014 using Multinomial logit model. The results are summarized as follows. First, factors such as age, income, employment status, and educational level were found to be statistically significant upon the impact analysis of consumers' demographic characteristics. Second, the study showed that the first group of consumers drinking less coffee and tea had the highest interest in health, followed by the third group drinking less coffee and more tea, the second group more coffee and less tea, and the fourth group more coffee and tea. In addition, it was also found that the fourth group's pattern to purchase more coffee and tea could be explained by consumers' food consumption patterns.
