Type 2 diabetes mellitus (T2DM) is one of the most prevalent chronic diseases amongthe elderly, which impairs their functionality and the quality of life. Since high levels of socialisolation are observed in the elderly population, we hypothesized that low social support network (SSN) could have negative effects in clinical evolution of T2DM. Therefore, the practiceof socio educational activities could contribute to a favorable disease control and improvement of T2DM clinical parameters.AimsWe evaluated, cross-sectionally and retrospectively, the relationship of SSN size withmetabolic parameters of TD2M and the influence of socio-educational activities (i.e. crafts,jewelry, fitness, literacy, dance, guitar, singing, ballroom dancing, theater, yoga, flamenco,among others) in changes of the glycemic and lipid indexes in elderly patients (> 60 yearsold).MethodsSix clinical parameters, fasting blood glucose (FBG), glycated hemoglobin (HbA1c),circulating triglycerides, HDL, LDL and total cholesterol levels were compared with socialsupport network (SSN) which was measured in 89 T2DM patients by minimal map of relationship in older people (MMRI). The same parameters were compared between the grouppracticing socio educational activities (n = 23) and non-practicing group (n = 33). The changes in values were established between two phases: 2001 to 2009 (before) and 2010 to 2011(after), in both groups. The results were analyzed in two ways: a) vertical comparison ofthe averages of each individual clinical parameter; and b) horizontal comparison of total improvement rate (TIR), resulting from the sum of the individual improvement rate (iIR). Tocalculate iIR, clinical improvement received an arbitrary value (0.25) whereas no clinicalimprovement was ascribed a 0 value.ResultsWe observed a discrete positive correlation between SSN size and glycemic control improvement of elderly T2DM patients. When socio-educational interventions are evaluated, weobserved a significant improvement in HbA1c levels of up 34.5% (odds ratio=4.25; 95% CI,1.17 - 15.45; p = 0.0535) in elderly diabetics practicing socio educational activities. However,the fasting glucose and total cholesterol values had no significant improvement. In the otherhand, the horizontal analysis showed a significant difference between IMT means from elderly diabetics practicing socio educational activities when compared to the control group (p =0.03). It was observed a greater number of cases of clinical improvement over 50% (IMT 0.75and 1.0) in the socializing group (66% vs 36%).ConclusionsOur results suggested an apparent relationship between high SSN and practices of socio educational activities with significantly improvement of glicaemic control elderly T2DMpatients. We speculated that enhancing social support affects direct or indirectly some health-related variables, although potential pathways activated by social and educational components to regulating glucose metabolism remains unclear. However, our data are suggestingthat inclusion of socio-educational elements as non-pharmacological strategies for glicaemiccontrol may contribute for an effective management of T2DM in public health.
