differences that makes one study more usefull then the other.
"Dairy consumption and risk of type 2 diabetes mellitus in men"
Arch Intern Med. 2005 May 9;165(9):997-1003.
"Follow-up Study. RESULTS: During 12 years of follow-up, we documented
1243 incident cases of type 2 diabetes. Dairy intake was associated
with a modestly lower risk of type 2 diabetes. After adjusting for
potential confounders, including body mass index, physical activity,
and dietary factors, the relative risk for type 2 diabetes in men in
the top quintile of dairy
intake was 0.77 (95% confidence interval [CI], 0.62-0.95; P for trend,
..003) compared with those in the lowest quintile. Each serving-per-day
increase in total dairy intake was associated with a 9% lower risk for
type 2 diabetes (multivariate relative risk, 0.91; 95% CI, 0.85-0.97).
The corresponding relative risk was 0.88 (95% CI, 0.81-0.94) for
low-fat dairy intake and 0.99
(95% CI, 0.91-1.07) for high-fat dairy intake. The association did not
vary significantly according to body mass index (< 25 vs or = 25
kg/m(2); P for interaction, .57). CONCLUSION: Dietary patterns
characterized by higher dairy intake, especially low-fat dairy intake,
may lower the risk of type 2 diabetes in men."

the metabolic syndrome: findings from the British Women's Heart and Health
Study.Lawlor DA, Ebrahim S, Timpson N, Davey Smith G.
Department of Social Medicine, University of Bristol, Canynge Hall, Bristol,
UK.Objective To examine the association of milk consumption with insulin
resistance and the metabolic syndrome. Methods The association was examined
in 4024 British women aged 60-79 who were randomly selected from primary
care centres in 23 towns. Results Women who never drank milk had lower
homeostasis model assessment insulin resistance (HOMA) scores, triglyceride
concentrations and body mass indices, and higher high-density lipoprotein
(HDL)-cholesterol concentrations, than those who drank milk. The
age-adjusted odds ratio for the metabolic syndrome comparing non-milk
drinkers with drinkers was 0.55 (0.33, 0.94), which did not attenuate with
adjustment for potential confounders. Diabetes was less common in non-milk
drinkers. Conclusion Individuals who do not drink milk may be protected
against insulin resistance and the metabolic syndrome. However, randomized
controlled trials are required to establish whether milk avoidance is
causally associated with these outcomes. Diabet. Med. 22, 808-811 (2005).PMID: 1591063
