RESUMO

Objective To evaluate the effect of information-knowledge-attitude-practice (IKAP) theory-based health education interventions on clonorchiasis control among community residents and primary school students in Torch High-tech Development Zone of Zhongshan City, so as to provide insights into formulation of clonorchiasis control strategies among different types of populations. Methods Residents were randomly sampled from two communities and students from two primary schools using a random cluster sampling method in Torch High-tech Development Zone, Zhongshan City from 2019 to 2021, and health education pertaining to clonorchiasis control was performed based on the IKAP theory. The changes in the awareness of basic clonorchiasis control knowledge and belief, self-reported risk of Clonorchis sinensis infections and dietary behaviors were compared among community residents and primary school students before and after health education interventions. Results The participants included 146 male and 151 female community residents and 158 male and 153 female primary school students, with no significant difference detected in gender distribution (χ2 = 0.16, P > 0.05). The mean awareness of basic clonorchiasis control knowledge increased by 44.71% and 43.28% among primary school students and community residents 6 months following health education, and there were significant differences in the awareness of each item of basic clonorchiasis control knowledge before and after health education (χ2 = 41.53 to 284.44, all P values < 0.05). The proportions of primary school students and community residents thinking very high and high risks of C. sinensis infections increased from 9.35% and 6.71% before health education to 22.15% and 37.75% after health education, but only the difference of the attitudes in community residents achieve statistical significance (χ2 = 92.18, P < 0.05). The frequency of separation of raw and cooked foods with chopping board and knife significantly increased among community residents and primary school students following health education (χ2 = 16.04 to 62.65, all P values < 0.05). The frequency of eating raw freshwater fish (χ2 = 32.85, P < 0.05), fish congee (χ2 = 7.02, P < 0.05) and fish fillet hot pot (χ2 = 4.88, P < 0.05) significantly reduced among primary school students following health education, while only the frequency and proportions of eating raw freshwater fish have significantly reduced in community residents (χ2 = 11.77, P < 0.05). Conclusions Health education interventions based on the IKAP theory are effective to increase the awareness of clonorchiasis control knowledge and improve dietary behaviors associated with C. sinensis infections among community residents and primary school students in Zhongshan City.

RESUMO

<p><b>OBJECTIVE</b>To evaluate the association between occupational stress, social support, and occupational unintentional injuries.</p><p><b>METHODS</b>A 1:1 matched case-control study was conducted in 151 cases of occupational unintentional injuries who were admitted to 6 occupational injury-admitted hospitals in Zhongshan City from October 2013 to December 2013 and 151 matched controls without unintentional injuries in the last year who had matched age, sex, and occupation. Their demographic characteristics, occupational stress (by the effort-reward imbalance questionnaire), and social support were investigated with a structured questionnaire.</p><p><b>RESULTS</b>Analysis of the data showed that there were significant differences in the score of each dimension of occupational stress, the ratio of effort to reward, and the score of superior support between the case group and the control group (P < 0.05). The Cox regression analysis results showed that more extrinsic efforts (OR = 1.47, 95%CI = 1.20∼1.80) and over commitment (OR = 1.30, 95%CI = 1.08∼1.55) were the risk factors for occupational unintentional injuries, while more superior supports (OR = 0.64, 95%CI = 0.48∼0.84) and higher earnings (>3 000 yuan each month) (OR = 0.67, 95%CI = 0.54∼0.84) were protective factors.</p><p><b>CONCLUSION</b>Occupational stress and social support have an influence on the occurrence of occupational injuries.</p>

RESUMO

<p><b>OBJECTIVE</b>To evaluate the occupational safety climate in different types of enterprises and its relationship with occupational accidental injury.</p><p><b>METHODS</b>A cross-sectional survey based on self-report questionnaires was performed among 3311 front-line workers from 54 medium and small-sized manufacturing enterprises of different types in Zhongshan, China to investigate the socio-demographic characteristics, safety climate experience in workplace, and incidence of occupational accidental injury in the past year.</p><p><b>RESULTS</b>Analysis of the data revealed that employees in different types of companies perceived different levels of safety climate, according to the scores on four subscales; the European and American enterprises had significantly better safety climate than the Hong Kong and Chinese private enterprises (P < 0.01). The self-reported rates of occupational injury were 3.38%, 4.76%, and 6.72%, respectively, for European and American, Hong Kong, and Chinese private enterprises (χ(2) = 6.78, P < 0.05). After control of such factors as age, sex, income, education level, and marriage, the logistic regression analysis showed that the risk of occupational accidental injury in the European and American enterprises was significantly lower than that in the Chinese private enterprises (OR = 0.57, 95%CI = 0.35-0.91).</p><p><b>CONCLUSION</b>The type of enterprise influences the occupational safety climate and incidence of occupational injury among workers.</p>

RESUMO

<p><b>OBJECTIVE</b>To determine the prevalence of occupational musculoskeletal disorders (OMSD) and its risk factors among workers in three manufacturing industries in Zhongshan, China by cross-sectional epidemiological investigation.</p><p><b>METHODS</b>A total of 2 035 workers from the industries of metals (1001 persons), electrical appliances (455 persons), and furniture (579 persons), including 1 402 males and 633 females, were selected; the mean age was 32.9 ± 8.2 years, and the mean length of service was 6.4 ± 5.6 years. A revised Northern Europe Standardized Questionnaire was used for cross-sectional epidemiological investigation of OMSD.</p><p><b>RESULTS</b>The results showed that OMSD in these workers was primarily located in the neck, waist, and shoulder, with annual prevalence rates of 23.1%, 20.1%, and 15.8%, respectively. The overall prevalence of OMSD was 43.1% in metal industry, 44.0% in electrical appliance industry, and 26.6% in furniture industry. OMSD prevalence showed significant differences between different industries (χ(2) = 54.2, P < 0.01). The prevalence of OMSD in the shoulder and back increased with working years (P < 0.05). Logistic regression analysis showed that the risk factors for OMSD were working age >10 years, safety behavior such as "bending down when lifting heavy things from the ground", and different types of industries.</p><p><b>CONCLUSION</b>OMSD is mainly manifested by neck pain, waist pain, and shoulder pain among front-line manufacturing workers in Zhongshan, and working age, poor labor posture, and different types of industries were risk factors for waist pain.</p>

RESUMO

Objective: To study the relationship between vitamin A (VA) supplementation and the level of IgG antibody to measles strengthened vaccination. Method: Fifty-three school children aged 5-13 years were selected as the test group of VA supplementation, and fifty-two school children as the control group whose ages and sex matched with the test group. The test group was supplicd po the VA pills (2 500IU) at the same time with measles strengthened vaccination for one month. The level of serum VA was analyzed by HPLC. Measles antibody IgG was detected by ELISA. Results: One month after VA supplementation, sernm VA in test group was 376.5?74.2 ?g/L, showing statistical increase over before. The positive rates of measles antibody in the test group were increased from 69.8% to 100%, and the protective rate from 5.6% to 60.4%. The positive rates of measles antibody in the control group were increased from 71.2% to 100%, and the protective rates from 0% to 17.4%. The protective rate in the test group was statistically higher than the control. Conclusion: Simultaneous VA supplementation (especially for the children of VA deficiency) and measles strengthened vaccination contribute to the increase of measles antibody IgG in school children.
