Comparison between residential HCWs, HHWs and reference groups were conducted using analysis of variance (ANOVA) for continuous variables, with post hoc Tukey's test, and [Chi.sup.2] test for dichotomous variables.
In general, cumulative prevalence of MSD morbidity was 17% in the reference group and 28.3% in exposed groups (Table 3): in particular, a prevalence of 20% was identified in the HCWs group with MAPO index 0-5 and 34% in the group with MAPO index [greater than or equal to] 5.01; in HHWs, the cumulative prevalence was 31%.
In particular, HCWs with MAPO index [greater than or equal to] 1.51 and HHWs [greater than or equal to] 50 year old reported a cumulative MSD prevalence of 54.3% and 50%, respectively.
Focusing on the affected locations, HHWs and HCWs with MAPO index [greater than or equal to] 5.01 had similar prevalence of NBP in cervical region (9% and 11%, respectively), with a reduced prevalence in HCWs MAPO 0-5 group (6%).
At lumbosacral level, prevalence of NBP was similar in both residential HCWs groups (21% in MAPO index 0-5 group and 25% in MAPO index [greater than or equal to] 5.01 group) and higher in the HHWs group (31%).
In regression analysis (Table 4), MSD complaints were more frequent in HHWs and HCWs of the group MAPO [greater than or equal to] 5.01 (OR = 2.194, 95% CI: 1.251-3.847 and OR = 2.515, 95% CI: 1.445-4.378) than in residential HCWs with lower MAPO (OR = 1.221, 95% CI: 0.661-2.254) and reference groups.
--searching the patents and making comparative analysis of innovative technologies on the RES usage for HHWS systems;
--developing several options of constructive technological scheme of HHWS system on the basis of RES use for distributed objects taking into account different climate conditions of the Republic of Kazakhstan;
--creating a complex system of HHWS with the remote control on the university exercise area.
Science practical bases of creation of the HHWS system on the base of using RES with remote control for distributed objects taking into account climate conditions of the Republic of Kazakhstan will be developed.
The prototype of HHWS system with remote control will be created in the university's study area as well.
