Introduction: Insulin resistance is a feature of a number of clinical disorders, including T2D/glucose intolerance, obesity, dyslipidaemia and hypertension clustering in the so-called metabolic syndrome. Insulin resistance in skeletal muscle manifests itself primarily as a reduction in insulin-stimulated glycogen synthesis due to reduced glucose transport. 
Material and Method: A cross-sectional study was conducted on 100 subjects of type 2 diabetes having an age group of 40-70 years from urban and rural area of Meerut, U.P., India for determination of HOMA-estimated insulin resistance (HOMA-IR).
Result: We found   urban subjects had significantly higher fasting Glucose, fasting insulin and HOMA-IR values than rural subjects (p < 0.001).
Conclusion: Environmental and lifestyle changes resulting from industrialization and migration to urban environment from rural settings may be responsible to a large extent, for this epidemic of insulin resistance in Indians.

Aim: To investigate the relation of vitamin D concentration and parathyroid hormone with
insulin resistance in PCOS women.
Methods: In the department of Obstetrics and Gynecology at Dr. Baba Saheb Ambedkar
Medical College & Hospital, Rohini, Delhi, a one-year observational study was conducted.
The levels of 25, hydroxyvitamin D and PTH, as well as the levels of fasting sugar and
insulin in the blood, were tested.
Results: There was a 91.0 percent prevalence of vitamin D insufficiency (<20 ng/ml) in the
study, whereas 67.9 percent of participants had an elevated parathyroid hormone level.
According to the study, vitamin D insufficiency (r=-0.64, p=0.01) had a significant negative
connection with the HOMA-IR. Increased PTH levels were shown to have a positive
correlation with HOMA-IR.
Conclusion: Women with PCOS who have high parathyroid hormone levels or vitamin D
insufficiency have a higher incidence of glucose intolerance.
If vitamin D insufficiency and insulin resistance are strongly linked, it may be possible to
treat insulin resistance by raising vitamin D levels.
