Soo Kyung Kang
Abstract
In this study, a meta-analysis was made of 23 papers on skin conditions-related variables. The followings show the results. First, 13(56.65%) out of 23 papers were masters` theses; 13(56.5%) were conducted on university students; 20(87.05%) on women. Second, in 13(56.5%) out of 23 papers the skin test was performed by the use of equipments; in 10(43.5%) it was performed by subjective evaluation. The number of subjects was significantly more in subjective evaluation than in mechanical evaluation. Mechanical evaluation was adopted not only in all the doctoral theses but in 9(69.2%) out of 13 theses published in 2006 and afterwards. Third, in relation to independent variables, 18 theses (78.3%) adopted the eating habits; 14(60.9%) favorite foods; 12(52.2%) exercise; 10(43.5%) skincare habits and stress; 9(39.1%) slumbers. Resultantly, ultra violet 4(100%), in 17 theses (94.4%) eating habits showed the highest significance level; in 8(80.0%) skin care habits; in 10(71.4%) favorite foods; in 8(66.7%) exercise; in 6(60.0%) stress; in 5(55.6%) slumbers. Fourth, in eating habits, Vitamin, regular mealtime and water ingestion were adopted as positive factors for skin conditions. On the other hand, heavy meals, spicy, salt, instant and high-calorie foods were adopted as negative factors for skin conditions. Eight hours of slumber and regular exercise were adopted as positive factors, but ultra violet, stress, excessive coffee intake, smoking and drinking were adopted as negative factors. In relation to skin care habits, specialists` care, right care and regular massages were adopted as positive factors.
