Associations among oily taste preference, obesity, dyslipidemia, and metabolic syndrome in Korean adults

Abstract

This study was performed to investigate the nutrient intake, anthropometric measurement, serum lipid profiles, obesity, dyslipidemia, and metabolic syndrome according to oily taste preference. The data for this study was obtained from the Anseong and Ansan Cohort Study, which is a part of the Korean Genome Epidemiology Study (KoGES). The data was composed with epidemiological information, such as demographic surveys, history of past diseases, and biochemical examinations and dietary intake. The subjects of this study were 8,322 Korean (3,975 men and 4,347 women) aged between 40 and 69 years. Subjects were classified into three groups based on their oily taste preference; Dislike (n = 4,233), Moderate (n = 1,997), and Like (n = 1,478). As statistical analyses, Chi square test, One-way analysis of variance (ANOVA), Duncan's multiple range test were performed using SPSS (P<0.05). There were significant differences in sex (P<0.001), age (P<0.001), alcohol drinking (P<0.001), cigarette smoking (P<0.001), hypertension medication status (P=0.004), and diabetes medication status (P=0.004) by oily taste preference. The Like group had significantly higher averages of weight, waist circumference, body mass index (BMI), fat mass, and lean body mass compared to the Dislike group. Moreover, the levels of blood total cholesterol, LDL-C, TG, and HOMA-IR were significantly higher in Like group compared to those of Dislike group. Like group showed a high proportion of obesity, dyslipidemia, and metabolic syndrome. Also, the proportion of energy intake from carbohydrate and fat were significantly higher in Like group, but compared to Dislike group. the proportion of subjects whose intakes were less than 75% of EAR (Estimated Average Requirement) for energy was to be lower in Like subject group. In conclusion, oily taste preference seemed to be associated with higher level of obesity, dyslipidemia, and metabolic syndrome with increased intake of energy in Korean adults. ;본 연구는 기름진 맛 선호도에 따라 영양섭취, 신체계측, 혈청 지질 농도, 비만, 이상지질혈증, 대사증후군을 조사하기 위해 수행되었다. 자료는 한국인유전체역학조사사업 (KoGES)의 일환인 안성안산 코호트 조사로부터 얻었으며 이는 신체계측조사, 과거질환력, 생화학적 검사를 포함한 역학정보로 구성되었다. 조사대상자는 40-69세의 한국인 남성 3,975명, 여성 4,347명 총 8,322명으로 이루어졌다. 대상자는 기름진 맛 선호도에 따라 선호군 (n=1,478), 보통군 (n=1,997), 비선호군 (n=4,233)의 세 군으로 분류하였다. 통계 분석으로는 SPSS를 이용하여 Chi square test, 일원배치 분산분석 (ANOVA), Duncan's multiple range test를 수행하였으며 P값이 0.05미만일 때 통계적으로 유의하다고 하였다. 기름진 맛 선호도에 따라 성별(P<0.001), 연령(P<0.001), 음주여부 (P<0.001), 흡연여부 (P<0.001), 고혈압 (P=0.004) 및 당뇨약 복용 여부 (P=0.004)에서 유의적인 차이가 있었다. 체중, 허리둘레, 체질량지수, 체지방량과 제지방량은 선호군이 비선호군에 비하여 유의하게 높았으며, 혈액에서 총 콜레스테롤, LDL-콜레스테롤, 중성지방, HOMA-IR은 선호군이 비선호군보다 유의하게 높았다. 또한 비만, 이상지질혈증, 대사증후군의 비율은 선호군이 비선호군보다 유의하게 높았다. 탄수화물과 지방으로부터 에너지의 섭취 비율은 선호군이 비선호군보다 유의하게 높았으나 에너지의 평균필요량의 75% 미만인 비율은 선호군이 더 낮았다. 결론적으로 기름진 맛 선호도는 한국 성인에서 에너지 섭취 증가와 비만, 이상지질혈증, 대사증후군과 관련성이 높을 것이라고 보여진다.
