| Objectives We aims at improving steel worker’s knowledge of the metabolic syndromeand change their attitudes and behaviors to it by taking the comprehensive interventionmeasurement so as to provide a theoretical basis for exploring effective intervention modelof metabolic syndrome.Methods In A subsidiary Plant1and Plant2of some Iron and Steel Group LimitedCompany,281workers whose length of service is more than one year were selected assubjuects from two factories by cluster sampling method respectively. The workers fromplant1were selected as experimental group and the workers from plant2were selected ascontrol group. A baseline survey was conducted in two groups of workers. The surveycontents included occupational factors, personal medical history, physiological andbiochemical indicators of metabolic syndrome and the knowledge, beliefs and behaviors ofprevention and treatment of metabolic syndrome and so on. The experimental group wasgiven six-month comprehensive intervention such as health education at that time, oneweek, two weeks, one month, three months and six months respectively. The control groupwas not given any intervention. After the end of the intervention, two groups werereinvestigated with the same questionnaire Database was build up with Epidata3.0, and thestatistics analysis were made by SPSS17.0software package. The difference between twogroups in blood pressure before and after the intervention, blood glucose, blood lipidsknowledge, attitude, behavior changes and metabolic syndrome were tested by t-test orChisquare test.Results1281workers were investigated in the experimental group and the control grouprespectively. The average age of experimental group and that of control group was41.5±8.2years and41.0±7.6years respectively. High school or college educationaccounted for50.0%and48.2%respectively in two groups. The average length of serviceexperimental group and the control group was21.6±9.1years and21.4±8.7years. Therewas no significant difference in age, education, seniority, job between two groups.2Before the intervention, the two groups’ physiological and biochemical parameters showno significant difference (P>0.05) but they are comparable; after the intervention, diastolicblood pressure decreases more significantly in the experimental group than the controlgroup, and the difference is statistically significant (P<0.05), whereas the difference beforeand after the intervention in BMI, waist circumference, systolic blood pressure, fastingglucose TG and HDL-C in the experimental group, is not statistically significant comparedwith the control group(P>0.05).3There was statistically significant difference in theawareness of diagnostic criteria of hypertension, hyperglycemia diagnostic criteria, bloodlipid, MS risk factors, MS complications and nutritional meals, and cheerful knowledgepreventing metabolic syndrome, and the change rate in the experiment group was higher than that of the control group (P<0.05).4The change number of people who were willingto accept the intervention of health education and to aquire actively the knowledge of MSin the experiment group were higher than those of the control group Before and after theintervention (P<0.05).5The change rate of drinking and addicted salty in the experimentgroup was greater than those of the control group(P<0.05). But the change of rates had nosignificant difference in quit smoking and p exercise between the two groups(P>0.05). Thechange of rates with consumpation of eggs, meat, soy products, vegetables, fruits, wholegrains and other habits was significant difference between the two groups(P<0.05).6Before the intervention, the difference in knowledge, beliefs, behavior and the averagescore is not statistically significant between the two groups (P>0.05), but they arecomparable. After the difference in intervention, knowledge, beliefs, and the average scoreis statistically significant (P<0.05), which needs to be conducted stratified analysis,showing that age is related with the average score of knowledge (P<0.05), and they needpairwise comparisons. It proves that the difference in the average score of MS knowledgein the experimental group whose ages are30to40years, is statistically significantrespectively (P<0.05). Before and after the intervention in the experimental group, thedifference in knowledge and belief scores is statistically significant compared with thecontrol group (P<0.05). By conducting stratified analysis, it reveals that age is related withknowledge, thus affecting intervention effect (P<0.05), and they need pairwisecomparisons showing that in the age group of30to40-year-old group of workers, beforeand after MS intervention, the average score difference is statically significant (P<0.05).764.49(the GI index of comprehensive score) after intervention was greater than42.74before intervention in study group. Compared to control group,64.49was also higher than52.03(the GI index) in control group.Conclusions1The comprehensive intervention of the main health education andbehavioral intervention is effective in improving the awareness of the steel rolling plantworkers MS-related knowledge, and changing the beliefs and the behaviour bad habitssuch as drinking, addicted to salty, not to eat whole grains, soy.2This comprehensiveintervention tested is effective by the comprehensive evaluation method. |
