Aim: To assess risk factors for development of type II diabetes. Materials & Methods: 80 patients of type 2 diabetes mellitus >40 years of age were put in group 1 group 2 were healthy subjects irrespective of gender. Factors such as family history, physical activity, blood pressure, alcohol consumption and BMI was recorded. Results: Alcohol consumption was present in 45 in group 1 and 20 un group 2, family history was positive in 65 group 1 and 12 in group 2, sedentary life was seen in 52 group 1 and 25 in group 2, BMI was underweight seen in 14 in group 1 and 5 in group 2, normal 12 in group 1 and 46 in group 2, overweight 30 BMI was underweight seen in 14 in group 1 and 5 in group 2, normal12 in group 1 and 14 in group 2 and obese 22 and 15 46 in group 2. Blood pressure was normal seen 16 in group 1 and 42 in group 2, pre- hypertension 24 in group 1 and 26 in group 2, hypertension stage 1 in 30 in group 1 and 10 in group 2 and hypertension stage 2 seen in 10 in group 1 and 2 in group 2. A significant difference was observed (P< 0.05). Conclusion: Common risk factors in diabetes was overweight, hypertension, lack of physical activity and alcohol consumption.
Diabetes mellitus type 2 (DM2) is a metabolic disorder of multiple etiologies due to disturbances of carbohydrate, fat, and protein metabolism [1]. It is characterized by chronic hyperglycemia, and it is associated with cardiovascular and renal complications. These complications result in diminished quality of life and reduced life expectancy [2]. In addition, the disease places a considerable economic burden on worldwide healthcare resources [3]. The estimated number of deaths due to diabetes is similar to the combined number of deaths from several infectious diseases such as human immunodeficiency virus (HIV)/AIDS, malaria, and tuberculosis [4].
The estimated diabetes prevalence worldwide for 2010 was 285 million people corresponding to 6.4% of the world’s adult population [5]. By 2030, 438 million (7.8%) people of the adult population is expected to have diabetes similarly; for India, this increase is estimated to be 87 million in 2030 [6]. Insulin helps sugar get into cells to maintain normal blood sugar (glucose) levels. It often begins after the age of 40 years, but age range can start from 20+ years [7] The prevalence of type 2 diabetes is increasing globally and represents a heavy burden on public health and socioeconomic development of all nations. Type 2 diabetes is a multifactorial disease and due to a combination of environmental and genetic risk factors (many environmental risk factors contribute to the pathogenesis of type 2 diabetes, including lifestyles such as sedentary behavior, diet, smoking and alcohol consumption, internal environmental factors such as inflammatory factors, adipocytokines and hepatocyte factors, external environmental factors such as environmental endocrine disruptors) [8].
Genetic base in type 2 DM is complex and incompletely defined. So no isolated known defect predominates, as is the case with HLA connection with type 1 DM. Type 2 DM is more common in certain ethnic and racial groups [9]. Considering this, the present study aimed at assessing risk factors for development of type II diabetes.
Patients were randomized into two groups. Group 1 were type 2 diabetes mellitus patients and group 2 were healthy subjects irrespective of gender. A 5ml venous blood was drawn and collected in a test tube for assessment of fasting blood glucose level. A value more than 126 mg/dl considered diabetics. Glycosylated blood glucose level above 6.4% was designated as diabetes. Factors such as family history, physical activity, blood pressure, alcohol consumption and BMI was recorded. Results of the present study after recording all relevant data were subjected for statistical inferences using chi- square test. The level of significance was significant if p value is below 0.05 and highly significant if it is less than 0.01.
Group 1 had 50 males and 30 females and group 2 had 40 males and 40 females (Table 1).

| Status | Diabetes | Healthy |

From Table 2 and Figure 1, we can observe that the alcohol consumption was present in 45 in group 1 and 20 un group 2, family history was positive in 65 group 1 and 12 in group 2, sedentary life was seen in 52 group 1 and 25 in group 2, BMI was underweight seen in 14 in group 1 and 5 in group 2, normal12 in group 1 and 46 in group 2, overweight 30 BMI was underweight seen in 14 in group 1 and 5 in group 2, normal12 in group 1 and 14 in group 2 and obese 22 and 15 46 in group 2. Blood pressure was normal seen 16 in group 1 and 42 in group 2, pre- hypertension 24 in group 1 and 26 in group 2, hypertension stage 1 in 30 in group 1 and 10 in group 2 and hypertension stage 2 seen in 10 in group 1 and 2 in group 2. A significant difference was observed (P< 0.05).

In present study we assessed risk factors for development of type II diabetes. Nandimath et al., [16] determined the prevalent risk factors of type 2 diabetes mellitus and to estimate strength of association of these risk factors and occurrence of the disease. A total of 300 type 2 diabetes mellitus cases and 600 control subjects were included in this study. About 54.33% of cases were observed in the age group of >40-50 years. About 69.66% were male and 30.34% female cases. There was significant association between modifiable risk factors and type 2 diabetes mellitus, while nonmodifiable risk factors (age, gender) were not significantly associated.
Our study demonstrated that alcohol consumption was present in 45 in group 1 and 20 un group 2, family history was positive in 65 group 1 and 12 in group 2, sedentary life was seen in 52 group 1 and 25 in group 2, BMI was underweight seen in 14 in group 1 and 5 in group 2, normal12 in group 1 and 46 in group 2, overweight 30 BMI was underweight seen in 14 in group 1 and 5 in group 2, normal12 in group 1 and 14 in group 2 and obese 22 and 15 46 in group 2. Begic et al., [17] evaluated questionnaires on the assessment of risk factors for Diabetes Mellitus type 2.
Analyzed questionnaires showed relatively low risk of getting diabetes in the next ten years in the majority of the population. These results are rather encouraging but may in some way be in confrontation with the statistics which show a rapid outburst of diabetes. Murad et al., [18] determined the common risk factors of diabetes mellitus type 2 (DM2) and the demographic background of adult Saudi patients with DM2. Known diabetic patients were recruited as cases, while nondiabetic attendants were selected as controls. A pretested designed questionnaire was used to collect data from 159 cases and 128 controls. Cases were more likely than controls to be men (P < 0.0001), less educated (P < 0.0001), natives of eastern Saudi Arabia (P < 0.0001), retired (P < 0.0001), lower-salaried (P < 0.0001), or married or divorced (P < 0.0001). By univariate analysis cases were likely to be current smokers (P < 0.0001), hypertensive (P < 0.0001), or overweight/obese (P < 0.0001). Cases were also more likely to have a history of DM in a first-degree relative (P = 0.020). By multivariate analysis, cases were more likely to be older than 40 years (P < 0.0001), less educated (P = 0.05), married or divorced (P = 0.04), jobless/housewives (P < 0.0001), or current smokers (P = 0.002). They were also more likely to have salaries.
We observed that Blood pressure was normal seen 16 in group 1 and 42 in group 2, pre- hypertension 24 in group 1 and 26 in group 2, hypertension stage 1 in 30 in group 1 and 10 in group 2 and hypertension stage 2 seen in 10 in group 1 and 2 in group 2. Rehman et al., [19] estimated the proportion of people with diabesity and assess the sociodemographic, dietary, and morbidity related factors associated with diabesity. The mean (standard deviation) age of 151 study participants was 58.2 (11.8) years with 66% (n = 100), 77% (n = 116) and 40% (n = 60) being females, sedentary workers and belonging to lower socioeconomic status, respectively. Of total, 71% (n = 107) had hypertension, 66% (n = 99) had uncontrolled fasting blood sugar (FBS) level and 74% (n = 111) did not consume fruits daily. The proportion of diabesity was found to be 66.9%. After adjusting for other factors, obesity was significantly high among T2DM patients aged 50 years and less 1.4; compared to >60 years. Having uncontrolled FBS values deficient in calorie intake deficient in fruits intake and high fat consumption had significant association with diabesity.
