T
he literature is suggesting an association between dairy
product consumption and insulin-resistance, however
results are inconclusive. To our knowledge, no study examined
this association in the Middle Eastern Region. The objectives
of this study are to examine the association between dairy
products’ consumption and insulin resistance in a sample of
Lebanese adults and to assess the effect of different types of
dairy products on insulin resistance.
This is a cross-sectional study conducted among Notre Dame
University employees, in Zouk Mosbeh, North and Shouf
campuses. Four questionnaires were administered including a
background and International Physical Activity Questionnaire
short form questionnaires, food frequency questionnaire and a
24h recall. Bioelectric Impedance Analysis was used tomeasure
percent body fat (PBF). Fasting insulin levels were measured
using Enzyme Linked Immunosorbent Assay technique.
Homeostatic Model Assessment for Insulin Resistance (HOMA-
IR) was used to quantify insulin resistance. A person with
HOMA-IR ≥ 2.5 was considered as insulin resistant. Statistical
analyses were performed using SPSS version 23. P< 0.05 was
considered to be statistically significant.
The sample consisted of 286 subjects (46.9 % men and 53.1
% women) with a mean age of 41.2±11.0 years. Average
dairy product intake in the total sample was 2.2 servings
per day. More than one third of participants (38.0%) were
insulin resistant with higher proportion of men (47.0%) being
insulin resistant compared to women (31.6%) (p=0.008).
After controlling for confounders, variables that were directly
associated with HOMA-IR when total dairy intake was included
in the model were gender (p=0.001), marital status (p=0.016)
and PBF (p<0.001) and inversely associated factors included age
(p=0.049) and low-density lipoproteins (p=0.041). The same
factors were associated with HOMA-IR, when the types of dairy
products were included in the model, in addition to yogurt
intake (p=0.021).
This study suggests that yogurt consumption, but not total dairy
consumption, was associated with increased insulin resistance.
Speaker Biography
Jessy El Hayek Fares joined the Department of Nursing & Health Sciences in fall 2012
shortly after completing her PhD and postdoctoral fellowship in Human Nutrition, at
McGill University, Canada, in Spring 2012. Currently El Hayek is teaching multiple graduate
and undergraduate courses including basic human nutrition, lifecycle nutrition as well as
community nutrition. As of fall 2014, she was appointed as chairperson of the Department
of Nursing & Health Sciences. El Hayek ‘s main research interests include repercussions of
low vitamin D status on bone health and other extra skeletal functions, particularly chronic
diseases.
