Japanese Adults

Background: Asians including Japanese are more susceptible to glucose intolerance or type 2 diabetes mellitus (DM) than Caucasians. However little is known about the effects of dietary fatty acid (FA) intake on insulin resistance (IR) in Japanese. Objective: Our aim was to investigate associations between IR and habitual dietary intake of FAs among middle-aged Japanese adults. Methods: We designed a cross-sectional survey of 3383 Japanese adults aged 35– 66 years. IR was measured with homeostasis model assessment (HOMA-R) and nutrient intake was estimated by a self-administered diet history questionnaire. All amounts of nutrients were energy-adjusted as the residuals from regression model. Results: Log-transformed HOMA-R had a significant negative correlation with polyunsaturated fatty acid (PUFA). Multivariate-adjusted regression analysis demonstrated that IR had a significant positive association with saturated fatty acid (SFA) and inverse associations with n-6 series PUFA independently of age, sex, BMI, lipid profiles, other macronutrients and lifestyle. Multivariate-adjusted odds ratios of IR, defined as a top quartile of HOMA-R distribution, across the quartiles of energy-adjusted intakes were 1.0, 0.89, 0.73 and 0.57 for linoleic acid ( P for trend = 0.007) and 1.0, 0.90, 0.68 and 0.61 for alpha-linolenic acid ( P for trend = 0.010), respectively. Marine-derived n-3 PUFA and the ratio of n-6 to n-3 PUFA had no consistent association with IR. Conclusions: Our cross-sectional data suggest that a modification of dietary fat intake to substitute PUFA, in particular linoleic acid and alpha-linolenic acid, for SFA may have a clinical efficacy to prevent IR among a Japanese population.

AbstractThe metabolic impact of circulating fatty acids (FAs) in patients requiring hemodialysis (HD) is unknown. We investigated the associations between plasma triglyceride (TG) FAs and markers of inflammation, insulin resistance, nutritional status and body composition. Plasma TG-FAs were measured using gas chromatography in 341 patients on HD (age = 55.2 ± 14.0 years and 54.3% males). Cross-sectional associations of TG-FAs with 13 markers were examined using multivariate linear regression adjusted for potential confounders. Higher levels of TG saturated fatty acids were associated with greater body mass index (BMI, r = 0.230), waist circumference (r = 0.203), triceps skinfold (r = 0.197), fat tissue index (r = 0.150), serum insulin (r = 0.280), and homeostatic model assessment of insulin resistance (r = 0.276), but lower malnutrition inflammation score (MIS, r =  − 0.160). Greater TG monounsaturated fatty acid levels were associated with lower lean tissue index (r =  − 0.197) and serum albumin (r =  − 0.188), but higher MIS (r = 0.176). Higher levels of TG n-3 polyunsaturated fatty acids (PUFAs) were associated with lower MIS (r =  − 0.168) and interleukin-6 concentrations (r =  − 0.115). Higher levels of TG n-6 PUFAs were associated with lower BMI (r =  − 0.149) but greater serum albumin (r = 0.112). In conclusion, TG monounsaturated fatty acids were associated with poor nutritional status, while TG n-3 PUFAs were associated with good nutritional status. On the other hand, TG saturated fatty acids and TG n-6 PUFAs had both favorable and unfavorable associations with nutritional parameters.

AbstractPaediatric non-alcoholic fatty liver disease has increased in parallel with childhood obesity. Dietary habits, particularly products rich in sugars, may influence both hepatic fat and insulin resistance (homeostatic model assessment for insulin resistance (HOMA-IR)). The aim of the study was to examine the association of the consumption of foods and food components, dairy desserts and substitutes (DDS), sugar-sweetened beverages (SSB), as well as total and added sugars, with hepatic fat and HOMA-IR. Dietary intake (two non-consecutive 24 h-recalls), hepatic fat (MRI) and HOMA-IR were assessed in 110 overweight/obese children (10·6 (sd 1·1) years old). Linear regression analyses were used to examine the association of dietary intake with hepatic fat and HOMA-IR adjusted for potential confounders (sex, age, energy intake, maternal educational level, total and abdominal adiposity and sugar intake). The results showed that there was a negative association between cereal intake and hepatic fat (β=–0·197, P<0·05). In contrast, both SSB consumption (β=0·217; P=0·028) and sugar in SSB (β=0·210, P=0·035), but not DDS or sugar in DDS or other dietary components, were positively associated with hepatic fat regardless of potential confounders including total sugar intake. In conclusion, cereal intake might decrease hepatic fat, whereas SSB consumption and its sugar content may increase the likelihood of having hepatic steatosis. Although these observations need to be confirmed using experimental evidence, these results suggest that healthy lifestyle intervention programs are needed to improve dietary habits as well as to increase the awareness of the detrimental effects of SSB consumption early in life.

We studied the effect of different levels of linseed oils made either of the flax cultivar Atalante with a high content of &alpha;-linolenic acid (612 g/kg) or of the cultivar Lola with a predominating content of linoleic acid (708 g/kg) in a chicken diet upon the fatty acid pattern in meat. Cockerels Ross 308 were fed the diets containing 1, 3, 5 or 7 per cent of oil in the last 15 days of fattening. Breast meat (BM) and thigh meat (TM) without skin of 8 chickens from each dietary group were used for analyses. The relative proportions of fatty acids were expressed as percentages of total determined fatty acids. When feeding Atalante oil, the proportions of n-6 fatty acids were highly significantly lower while those of n-3 fatty acids were higher; the ratio of n-6/n-3 polyunsaturated fatty acids in meat was narrower (<i>P</i> < 0.001) than in chickens fed oil with a low content of &alpha;-linolenic acid. In BM and TM, the relative proportions of &alpha;-linolenic and &gamma;-linolenic acids were nearly the same, the proportion of linoleic acid in BM was lower, and the proportions of the other polyunsaturated fatty acids in BM were higher than in TM. In BM, the ratio of n-6/n-3 polyunsaturated fatty acids was significantly (<i>P</i> < 0.001) more favourable than that found in TM. The relative proportions of total saturated and monounsaturated fatty acids in meat decreased and those of polyunsaturated fatty acids increased significantly (<i>P</i> < 0.01) in dependence on the increasing level of dietary oils. When feeding Atalante oil, a significant increase in the proportion of linoleic acid in BM but not in TM was observed. The proportions of the other n-6 fatty acids decreased and those of all determined n-3 fatty acids, with the exception of docosahexaenoic acid, significantly increased with the increasing level of oil in the diet. When feeding Lola oil, its increasing content in the diet increased the relative proportion of linoleic acid as well as its elongation to &gamma;-linolenic acid; however, the proportions of arachidonic and adrenic acid did not change significantly (<i>P</i> > 0.05). The proportion of &alpha;-linolenic acid increased in both BM and TM. The proportion of eicosapentaenoic and clupanodonic acids in BM significantly decreased. The ratio of n-6 to n-3 polyunsaturated fatty acids ranged from 0.9 to 13.6 and from 1.0 to 17.2 in BM and TM, respectively. An increase in the level of Lola oil in the diet by 1% caused that the n-6/n-3 polyunsaturated fatty acid ratio extended by 1.00 and 1.19 units in BM and TM, respectively. Dependences of n-6/n-3 ratio on the level of Atalante oil were expressed by equations of convex parabolas with minima at the level of oil 5.8 and 5.9% for BM and TM, respectively. By means of the inclusion of linseed oil with a high content of &alpha;-linolenic acid in the feed mixture it would be possible to produce poultry meat as a functional food with a very narrow ratio of n-6/n-3 polyunsaturated fatty acids.

ObjectiveResistin increases insulin resistance (IR) in mice. However, the role of resistin in human disease remains controversial. We aimed to assess plasma resistin levels and their associations with inflammatory and fibrinolytic markers, IR and metabolic syndrome (MetS) among Chinese.Design and methodsPlasma resistin was measured in a population-based cross-sectional survey of 3193 Chinese aged from 50 to 70 years in Beijing and Shanghai.ResultsThe median resistin concentration was 8.60 ng/ml (interquartile range, 5.78–14.00) among all participants, and it was higher in women than in men (P=0.008). Resistin was correlated weakly with body mass index, waist circumference, high-density lipoprotein (HDL) cholesterol (negatively), homeostatic model assessment of IR and tumor necrosis factor-α receptor 2 (TNFR2; r=0.04, 0.07, –0.09 and 0.06 respectively, all P<0.05), and more highly with C-reactive protein (CRP), interleukin (IL)6 and plasminogen activator inhibitor (PAI)1 (r=0.12, 0.12 and 0.21 respectively, all P<0.001), but only HDL cholesterol, CRP, IL6, TNFR2, and PAI1 remained significantly associated with resistin in multiple regression analysis (all P<0.05). Furthermore, elevated resistin levels were associated with the higher prevalence of IR and MetS. However, the significant relationships disappeared after adjustment for inflammatory and fibrinolytic markers especially PAI1.ConclusionsThis study suggests that resistin is more strongly associated with inflammatory and fibrinolytic markers than with obesity or IR status. The associations of resistin with IR and MetS could largely be explained by inflammatory and fibrinolytic markers especially PAI1 levels.

AbstractObjectiveTo examine the dietary intake of total sugar, added sugar, non-added sugar and starch as well as dietary fibre and glycaemic index (GI) and their respective associations with insulin resistance.DesignMixed linear models were used to study both cross-sectional and prospective associations between carbohydrate components and insulin resistance separately in girls and boys. Diet was assessed by a single 24 h recall interview and insulin resistance was calculated using the homoestasis model assessment (HOMA).SettingThe Danish part of the European Youth Heart Studies (EYHS) I and II.SubjectsGirls and boys at 8–10 and 14–16 years from EYHS I (n 651) and 8–10-year-olds from baseline followed up 6 years later in EYHS II (n 233).ResultsAmong girls, a difference in dietary total sugar of 43 g/MJ was associated with a 1 sd difference of HOMA and a difference in dietary fibre of −8 g/MJ was associated with a 1 sd difference of HOMA, independent of age, maturity and other confounders (both P = 0·03). No baseline associations were found among boys and no prospective associations were found in either sex.ConclusionsDietary intake of total sugar may play an adverse role and fibre may play a beneficial role in concurrent insulin resistance among girls but not boys. Sex differences may be due to differences in maturity, physical activity, food patterns and selective reporting behaviours.

Abstract Background The burden of insulin resistance (IR) among young American adults has not been previously assessed. We evaluated the 1) prevalence and trends of IR and cardiometabolic risk factors and, 2) assessed the association between measures of adiposity and IR among adults aged 18-44 years without diabetes and preexisting cardiovascular disease. Methods Cross-sectional survey data from six consecutive National Health and Nutrition Examination Survey (2007-2008 to 2017-2018) cycles were analyzed. IR was defined by the homeostatic model assessment for IR (HOMA-IR) of ≥2.5. The temporal trends of IR, cardiometabolic risk factors, and the relationship between IR and measures of adiposity were assessed using multivariable-adjusted regression models. Results Among 6,247 young adults aged 18-44 years, the prevalence of IR was 44.8% (95% CI: 42.0-47.6%) in 2007-2010 and 40.3% (95% CI: 36.4-44.2%) in 2015-2018 (Ptrend=0.07). There was a modest association of HOMA-IR with higher body mass index (BMI), waist circumference, total lean fat mass, and total and localized fat mass (all p&lt;0.001). Participants with IR had a higher prevalence of hypertension (31.3% [95% CI: 29.2-33.5%] vs. 14.7% [95% CI: 13.2-16.2%]), hypercholesterolemia (16.0% [95% CI: 12.4-19.5%] vs. 7.0% [95% CI: 5.8-8.5%]), obesity (56.6% [95% CI: 53.9-59.3%] vs. 14.7% [95%CI: 13.0-16.5%]) and poor physical activity levels (18.3% [95% CI: 16.4-20.2%] vs. 11.7% [95%CI: 10.3-13.1%]) compared to participants without IR (all p&lt;0.05). Conclusions Four-in-ten young American adults have IR, which occurs in a cluster with cardiometabolic risk factors. Nearly half of young adults with IR are non-obese. Screening efforts for IR irrespective of BMI may be required.

Abstract Background Cottonseed is one of the major sources of vegetable oil. Analysis of the dynamic changes of fatty acid components and the genes regulating the composition of fatty acids of cottonseed oil is of great significance for understanding the biological processes underlying biosynthesis of fatty acids and for genetic improving the oil nutritional qualities. Results In this study, we investigated the dynamic relationship of 13 fatty acid components at 12 developmental time points of cottonseed (Gossypium hirsutum L.) and generated cottonseed transcriptome of the 12 time points. At 5–15 day post anthesis (DPA), the contents of polyunsaturated linolenic acid (C18:3n-3) and saturated stearic acid (C18:0) were higher, while linoleic acid (C18:2n-6) was mainly synthesized after 15 DPA. Using 5 DPA as a reference, 15,647 non-redundant differentially expressed genes were identified in 10–60 DPA cottonseed. Co-expression gene network analysis identified six modules containing 3275 genes significantly associated with middle-late seed developmental stages and enriched with genes related to the linoleic acid metabolic pathway and α-linolenic acid metabolism. Genes (Gh_D03G0588 and Gh_A02G1788) encoding stearoyl-ACP desaturase were identified as hub genes and significantly up-regulated at 25 DPA. They seemed to play a decisive role in determining the ratio of saturated fatty acids to unsaturated fatty acids. FAD2 genes (Gh_A13G1850 and Gh_D13G2238) were highly expressed at 25–50 DPA, eventually leading to the high content of C18:2n-6 in cottonseed. The content of C18:3n-3 was significantly decreased from 5 DPA (7.44%) to 25 DPA (0.11%) and correlated with the expression characteristics of Gh_A09G0848 and Gh_D09G0870. Conclusions These results contribute to our understanding on the relationship between the accumulation pattern of fatty acid components and the expression characteristics of key genes involved in fatty acid biosynthesis during the entire period of cottonseed development.

Abstract Objectives Insulin resistance is the most common metabolic change associated with obesity. The present study aimed to investigate the relationship between insulin resistance and body composition especially adipose tissue in a randomized Tehrani population. Methods This study used data of 2,160 individuals registered in a cross-sectional study on were randomly selected from among subjects who were referred to nutrition counseling clinic in Tehran, from April 2016 to September 2017. Insulin resistance was calculated by homeostasis model assessment formula. The odds ratio (95% CI) was calculated using logistic regression models. Results The mean age of the men was 39 (±10) and women were 41 (±11) (the age ranged from 20 to 50 years). The risk of increased HOMA-IR was 1.03 (95% CI: 1.01–1.04) for an increase in one percent of Body fat, and 1.03 (95% CI: 1.00–1.05) for an increase in one percent of Trunk fat. Moreover, the odds ratio of FBS for an increase in one unit of Body fat percent and Trunk fat percent increased by 1.05 (adjusted odds ratio [95% CI: 1.03, 1.06]) and 1.05 (95% CI: 1.02, 1.08). Also, the risk of increased Fasting Insulin was 1.05 (95% CI: 1.03–1.07) for an increase in one unit of Body fat percent, and 1.05 (95% CI: 1.02–1.08) for an increase in one unit of Trunk fat percent. Conclusions The findings of the present study showed that there was a significant relationship between HOMA-IR, Fasting blood sugar, Fasting Insulin, and 2 h Insulin with percent of Body fat, percent of Trunk fat.
