Estimates of the present and future load of diabetes are essential in order to specify health and community resources, and to confirm the function of lifestyle, and promote measures to counteract directions for growing prevalence (Shaw et al., 2010).
A key notion in multilevel measurement approach is that theories, measures , and constructs must be harmonious. The introduction of interferences at multiple standards demands that the standard of measurement, standard of theory, and level/kind of statistical dissection be harmonious (Klein & Kozlowski, 2000).
The occurrence of kind 2 diabetes mellitus is growing worldwide (Neel, 1962). Type 2 diabetes often results from advanced fail of pancreatic β-cell role in the attendance of chronic insulin impedance (Buchanan et al., 2002).
However, the most dramatic increases in type 2 diabetes have occurred in societies where there have been prime and quick lifestyle alterations. These contain alterations in diet, and decreases in physical activity, together with consequent raises in the prevalence of obesity and overweight (Zimmet, 2001).
Kind 2 diabetes generates from the reciprocal action between environmental and behavioral risk agents and a genetic predisposition (Neel, 1962). The potential that diet may become a reason of diabetes has been realized for many years, even though the specific dietary agents that are entangled are yet to be defined (Hu et al., 2001).
The newly accomplished United Kingdom Prospective Diabetes survey has manifested that kind 2 diabetes mellitus is an advanced trouble that can be managed at the beginning with oral agent single therapy but will finally demand the addition of another oral agents, and as well that in several patients, insulin treatment will be required to accomplish targeted glycemic standards (DeFronzo, 1999).
Several anti-diabetic medicines with various procedures of action are now obtainable to treat kind 2 diabetes mellitus, containing sulfonylureas, thiazolidinediones, glinides, α-glucosidase inhibitors, and biguanides (Sola et al., 2015).
In addition, HbA1c measures have symbolized the gold level for the assessment of glycemic dominance in patients with diabetes for more than thirty years (Lippi & Targher, 2010).
My discussion of tactics for joining interventions at various standards is by no means tiresome. The fundamental point, is that multilevel interventions in my vision, should be designed established on sound causal thinking concerning the probable interactions among the integrated interventions and not plainly on the features of the person interventions themselves.

Most scientific proof about developing health and health patronage stems from single-level and single-site interferences, taking decades to proceed from clinical experiments to modern routines at clinic offices or bedsides (Steinbrook, 2006).
Multilevel intervention survey catches the promise of more precisely symbolizing real-life conditions than single-level intervention survey and, thence, with the proper survey measures and design, being more likely to assist the efficient and effective resolution of complicated health-care frameworks issues (Moore, 1994).
In our depiction of strategies for joining interventions at various standards, we differentiate three essential agents: interventions, settings, and targets. An intervention is actually a design for changing an offered state of affairs (Green et al., 1996; Richard et al., 1996).
Medical nutrition treatment as mentioned by American Diabetes Association et al., (2008):
Aims of Medical nutrition treatment that apply to people at danger for diabetes or who are with pre-diabetes:
To reduce the danger of diabetes and cardiovascular ailment by encouraging physical activity and healthy food options leading to intermediate weight lack that is preserved (ADA et al., 2008).
The late digestion of carbohydrates and split of oligosaccharides generates in undigested carbohydrates arriving bottom portions of the small intestine, as well inducing GLP-1 secretion there (Göke et al., 1995).
The insulin impedance that underlies kind 2 diabetes appears to generate primarily from lifestyle agents: physical inactivity and weight raise (Clausen et al., 1996).
It is probable that any kind of physical action — whether household work, sports, work-connected physical activity or gardening — is similarly useful in forbidding diabetes (Tuomilehto et al., 2001).
Another stimulus for a multilevel tactic is the persuasion that interventions are more probable to move successfully to other surroundings if study designs assist us perceive contextual agents that impact implementation (Zatzick et al., 2006).
MLI can contemplate other agents and standards that, if left unaddressed, render as possible unmeasured facilitators or obstacles to health-care developments (Charns et al., 2012).
Newly, incretin-related medicines, like (GLP-1) receptor agonists and as well (DPP-4) inhibitors, have been improved (Sola et al., 2015). The sulfonylurea medicine class has improved as various descents of agents (Marchetti & Navalesi, 1989).
AGIs might become a reasonable choice as initial-line medicine in the therapy of patients who have DM2 as it specifically aims at postprandial hyperglycemia, a potential independent risk agent for cardiovascular troubles (Ceriello, 2005).
Because of our attention in the causal connections between health results and the timing of MLIs, we think MLI research plans confirming longitudinal information collection and interventions inherently better than cross-sectional tactics (Alexander et al., 2012).

Anyway, an intervention aim relates to the standard of impact of the determinant (or in other words, causal agent) that an intervention tries to alter (Green et al., 1996; Richard et al., 1996).
Risk agents for Kind 2 diabetes can be categorized as modifiable and non-modifiable (Alberti et al., 2007). Anyway, Type 2 diabetes is induced by a collection of life-style and genetic agents (Kaprio et al., 1992).
Realization of the time required for alterations to permeate each level's members’ behavior and awareness is oftentimes underappreciated. For instance, several multilevel interventions depend on champions, which demands training/teaching of the champion and thereafter their constituents or peers (either by the project team or champion) via formal or informal public networks (Curran et al., 2005).
As demonstrated by Alberti et al., (2007), non-modifiable risk agents include: Age and gender, Genetic factors, and Previous gestational diabetes. Modifiable risk agents include: Obesity, Physical inactivity, Nutritional factors, and other risk factors.
Although the genetic foundation of kind 2 diabetes disease has yet to be recognized, there is powerful proof that such modifiable risk agents as physical inactivity and obesity are the prime nongenetic determinants of the ailment (Hamman, 1992; Manson et al., 1991; Stern, 1991). However, obesity is the prime known risk agent for diabetes (Harding et al., 2004).
Other chances for MLI survey are current in eHealth interventions, that have quickly replicated and can materialize jointly at the patient, community, and organizational standards (Clauser et al., 2011).

1) Metformin - Biguanide Group
Metformin is unambiguously the initial-line therapy in patients with kind 2 diabetes. It actually belongs to the biguanide group of drugs and performs by elevating hepatic insulin sensitivity (UKPDS Group, 1998).
Metformin is actually the most vastly prescribed initial-line factor for the management of kind 2 diabetes and as well, is standard initial-line pharmacotherapy, together with exercise and diet (Nathan et al., 2008).
2) DPP-4 Inhibitor Story
DPP-4 quickly deactivates and cleaves the incretin hormones (GIP) glucose-dependent insulinotropic polypeptide and as well, (GLP-1) glucagon-like peptide-1 (Augeri et al., 2005).
Saxagliptin is a strong, selective DPP-4 inhibitor, particularly designed for prolonged forbiddance of the enzyme - DPP-4 (Zhao et al., 2005). In preservation with the procedure of saxagliptin action, the extension of saxagliptin to metformin medicine did not elevate the occurrence of hypoglycemia condition versus that with metformin medicine alone, which is connected as usage of dipeptidyl peptidase 4 inhibitors in collection regimens becomes more passable (Amori et al., 2007).
The occurrence of microvascular problems from diabetes disease has been manifested to be meaningfully decreased with each 1% lowering in A1C; therefore, it is logical to propose that saxagliptin medicine added to metformin treatment would produce clinical advantages in expressions of risk decrease (Stratton et al., 2000).

5) Sulphonylureas
In spite of the big number of anti-diabetic factors obtainable, anyway, sulfonylureas stay the most widely utilized medicines for handling patients with kind 2 diabetes (Sola et al., 2015).
Sulfonylurea medicines link the sulfonylurea receptor, which is an ATP-sensible K+ channel, and prevent potassium efflux, which eases secretion of insulin (Aguilar-Bryan et al., 1995). What's more, Sulfonylureas are strong, glucose-independent insulin secretagogues that perform immediately on beta cells of pancreas (Panten et al., 1996).
The initial-descent sulfonylureas are actually the oldest, and contain chlorpropamide, tolbutamide, tolazamide, and acetohexamide. The second-descent sulfonylureas contain glyburide (also recognized as glibenclamide), glipizide, glimepiride, and gliclazide (Marchetti & Navalesi, 1989).
Regardless of the beneficial impacts of metformin in developing glycemic control, very oftentimes, anyway, metformin alone is inadequate for accomplishment of fine metabolic control. Oftentimes, as well, glycemic control damages in patients treated with metformin. This requires combination treatment by combining a secondary composition to metformin medicine. Most oftentimes, sulphonylureas are inserted (Nathan et al., 2006).
6) Glitazones
Glitazones develop insulin work in adipose, muscle, and hepatic tissue by performing like "agonists of peroxisome proliferator–activated receptor-γ (PPAR-γ) nuclear receptors". Stimulation of PPAR-γ produces in a great number of both vascular and metabolic impacts by downregulating and upregulating expression of abundant genes, containing genes recognized to organize glucose and lipid metabolism, vascular role, the inflammatory response, and thrombotic role (Miyazaki et al., 2001).
Glitazones also decrease blood pressure, develop lipid metabolism (decreasing triglyceride standards, elevating HDL cholesterol, and elevating concentrations of big, buoyant LDL particles), and as well develop vascular reactivity and rheologic malformations popular to insulin resistance and kind 2 diabetes (Parulkar et al., 2001).
