Dairy product consumption and its association with metabolic disturbance in a prospective study of urban adults

Abstract

The role of dairy foods and related nutrients in cardio-metabolic health etiology is poorly understood. We investigated longitudinal associations between the metabolic syndrome (MetS) and its components with key dairy exposures. We used prospective data from a bi-racial cohort of urban adults [30–64y at baseline (N=1,371)], the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS), in Baltimore City, MD (2004–2013). The average of 2 24-hour dietary recalls measured 4–10d apart was computed at baseline (V1) and follow-up (V2) waves. Annual rates of change (Δ) in dairy foods and key nutrients were estimated. Incident obesity, central obesity and metabolic syndrome (MetS) were determined. Among key findings, in the overall urban adult population, both cheese and yogurt (V1 and Δ) were associated with an increased risk of central obesity [HR=1.13, 95% CI:1.05,1.23 per oz equivalent of cheese (V1); HR=1.21, 95%CI: 1.01, 1.44, per fl oz equivalent of yogurt (V1)]. Baseline fluid milk intake (V1 in cup equivalents) was inversely related to MetS [HR=0.86, 95%CI: 0.78,0.94], specifically to dyslipidemia-triacylglycerol (TA) [HR=0.89, 95% CI:0.81,0.99], though it was directly associated with dyslipidemia-High Density Lipoprotein-Cholesterol (HDL-C), [HR=1.10, 95% CI:1.01,1.21]. Furthermore, Δcalcium and Δphosphorus were inversely related to dyslipidemia-HDL and MetS incidence, respectively, while Δdairy fat was positively associated with incident TA- and HDL-C-dyslipidemias and MetS. A few of those associations were sex- and race-specific. In sum, various dairy exposures had differential associations with metabolic disturbances. Future intervention studies should uncover how over-time changes in dairy components may affect metabolic disorders.

The association between milk consumption and the metabolic syndrome: a cross-sectional study of the residents of Suzhou, China and a meta-analysis

“…The characteristics of the included studies are summarised in online Supplementary Table S1. In the main meta-analysis of the present study and eleven other studies (15)(16)(17)(18)(21)(22)(23)(24)(27)(28)(29) , the pooled RR of the metabolic syndrome for the highest v. lowest categories of milk consumption was 0•80 (95 % CI 0•72, 0•88; Fig. 1), with high heterogeneity (I 2 73•5 %).…”

“…dairy product type, fat content and subpopulation) for this association have not been well elucidated. Evidence on the association between dairy consumption and the metabolic syndrome is predominantly derived from studies conducted in Western countries (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) , with only a few studies from Asian countries (19)(20)(21)(22)(23)(24) . Given that Asian populations differ from Western populations with respect to dietary pattern, cultural characteristics or amounts and types of dairy products consumed (25,26) , better understanding of the association between consumption of dairy product and the metabolic syndrome in Asian populations may provide valuable information that could be useful to refine the evidence on this topic.…”

Thus far, a number of studies have investigated the association between milk consumption and the metabolic syndrome in Western (15)(16)(17)(18)27) and Asian (21)(22)(23)(24)(28)(29)(30) populations. However, these studies have yielded inconsistent results, possibly due to the heterogeneity in study design, milk consumption levels and metabolic syndrome definition.…”

“…To the best of our knowledge, only two studies (29,30) have investigated this association in Chinese populations; however, both studies did not investigate the extent to which milk consumption may influence the metabolic syndrome components. Milk consumption may influence the metabolic syndrome components to different extents (18,(21)(22)(23) . We conducted a cross-sectional study to investigate the association between milk consumption and the metabolic syndrome and its components among the residents of Suzhou Industrial Park, which represent Southeast Chinese populations.…”
