A qualitative systematic review was performed to identify associations of obesity and dyslipidemia with intake of sodium, fat, and sugar among Koreans. We reviewed 6 Korean research databases (KMbase, KoreaMed, NDSL, DBpia, RISS, KISS) with the keywords “sodium intake,” “fat intake,” and “sugar intake.” Total of 11 studies were investigated in this present study. Of these articles, 7 studies were related to sodium intake, 2 studies had a relation to fat intake, and 2 studies were associated with sugar intake. We indicated general characteristics, concentration of serum lipids, nutrition intake, and statistically significant results. High sodium intake contributed to increased etiology of hypertriglyceridemia, high-density lipoprotein (HDL) hypocholesterolemia, and a risk of being overweight. Fat intake was significantly associated with body fat, low-density lipoprotein (LDL) hypercholesterolemia, and HDL hypocholesterolemia. Sugar intake from coffee drinks and sugar-sweetened beverages contributed to increased HDL hypocholesterolemia and continuous metabolic syndrome score. This qualitative review among Koreans represented that intake of sodium, fat, and sugar has a positive relationship with cause of obesity-related diseases. Especially, this present study has a great significance in terms of considered study that intake of the potentially hazardous nutrients among Koreans has an association with obesity and dyslipidemia. However, further studies such as randomized controlled trials on associations between sodium, fat, and sugar and obesity and dyslipidemia need to be continuously required in order to conduct quantitative systematic reviews and a meta-analysis for Koreans.
Background Hypertension (HTN) is the leading risk factor for cardiovascular mortality globally. The WHO estimates a 60% increase in Asian HTN patients between 2000 and 2025. Numerous studies have compared safety and efficacy between antihypertensive classes, but in-class comparisons of angiotensin II receptor blockers (ARBs) in combination therapy (CT) (fixed-dose combination or dual combination) with a calcium channel blocker (CCB) are lacking in Asia. Objective To compare the efficacy and safety of the various ARB-amlodipine CTs and amlodipine (AML) monotherapy for treatment of HTN in Asian population. Methods A systematic literature review sourced Asian randomized controlled trials (RCTs) from PubMed and Cochrane Libraries to inform a network meta-analysis (NMA). We considered the ARB-AML CT. The primary efficacy and safety endpoints were short-term (8–12 weeks) treatment response and treatment-emergent adverse events (TEAEs), respectively. AML monotherapy was used as a comparator to allow for indirect treatment effect estimation in the absence of direct RCTs evidence comparing the different ARB-AML CTs. Results The analysis included 1198 Asian HTN patients from seven studies involving six ARB-AML CTs: azilsartan (AZL), candesartan (CAN), fimasartan (FIM), losartan (LOS), olmesartan (OLM), and telmisartan (TEL). Compared to AML monotherapy, CT of AZL-AML had five times greater odds of prompting a treatment response (OR 5.2, 95% CI: 2.5, 11.2), while CAN-AML had 3.9 (95% CI: 2.5, 6.4), FIM-AML had 3.4 (95% CI: 1.4, 8.5), TEL-AML had 3.3 (95% CI: 1.6, 7.1), OLM-AML had 2.7 (95% CI: 1.6, 5.0), and LOS-AML had 2.0 (95% CI: 0.6, 7.3). All ARB-AML CTs had safety profiles comparable to AML monotherapy except TEL-AML, which had significantly lower odds of TEAEs (0.26 (95% CI: 0.087, 0.70)). Conclusion This study suggests that all ARB-AML CTs compared favorably to AML monotherapy regarding short-term treatment response in uncomplicated HTN patients of Asian origin. AZL-AML prompted the most favorable treatment response. Safety profiles among the ARB-AML CTs were largely comparable. Due to the limited study size and small number of trials (direct evidence), our findings should best be interpreted as an exploratory effort importance to inform future research direction.
Purpose: Excess sodium intake may contribute to the etiology of hypertension and cardiovascular disease risk. World Health Organization (WHO) recommends a daily sodium intake of less than 2 g. The aim of this study was to estimate the association of sodium intake with obesity in Korean adults. Methods: This study used Dietary intake and Health data on 22,321 subjects aged 30 years and over from the Korea National Health and Nutrition Examination Survey (KNHANES) 2010~2014. Information on dietary intake was obtained by the one day 24-hour recall method in KNHANES, and sodium intake was classified into five groups (< 2,000 mg, 2,000~4,000 mg, 4,000~6,000 mg, 6,000~8,000 mg, ≥ 8,000 mg). Obesity was defined as having a body mass index (BMI) higher than 25 kg/m 2 . Intake of sodium and obesity status were analyzed by logistic regression with SPSS Statistics 23. Results: Men tended to have a higher sodium intake than women (p < 0.001). After adjusting for age, sex, year, daily energy intake, education level, smoking status, drinking status, physical activity, and chronic diseases and comparing the highest sodium intake group (≥ 8,000 mg) with the lowest intake group (< 2,000 mg), the OR of obesity was 1.351 (95% CI: 1.032~1.767) in men. The OR of obesity in the sodium intake group (4,000~6,000 mg) was 1.232 (95% CI: 1.063~1.427) in women. Conclusion: Our findings suggest an independent relationship between sodium intake and as increased risk of obesity in Korean adults, implying the necessity for future research on low-sodium diet intervention in relation to obesity.
