RESUMO

To investigate the association between salt processed food and gastric cancer, a hospital based case-control study was conducted in a high risk area of China. One hundred and seven newly diagnosed cases with histological confirmation of gastric cancer and 209 controls were recruited. Information on dietary intake was collected with a validated food frequency questionnaire. Unconditional logistic regression was applied to estimate the odds ratios with adjustment for other potential confounders. Comparing the high intake group with never consumption of salt processed foods, salted meat, pickled vegetables and preserved vegetables were significantly associated with increased risk of gastric cancer. Meanwhile, salt taste preference in diet showed a dose-response relationship with gastric cancer. Our results suggest that consumption of salted meat, pickled and preserved vegetables, are positively associated with gastric cancer. Reduction of salt and salt processed food in diets might be one practical measure to preventing gastric cancer.

RESUMO

BACKGROUND: HIV transmission among men who have sex with men (MSM) has become an increasing concern in China. Money boys (MBs) are a subgroup of MSM who sell sex to men. Direct comparison of HIV prevalence and related risk factors between MB and noncommercial MSM (ncMSM) has rarely been done. This study was conducted to make the comparison. METHODS: Eight hundred fifty MBs and 801 ncMSM were parallel recruited in Shenzhen by time-location sampling. Their behavioral and serologic data on HIV and syphilis were collected and compared. Multiple logistic regression analysis was performed to evaluate the determinants for HIV risk in MBs and ncMSM, respectively. RESULTS: The prevalence of HIV was 4.5% in MBs and 7.0% in ncMSM. Although MBs tended to have more male partners than ncMSM, they were more likely to report a consistent condom use in male anal intercourse, especially in commercial sex. Noncommercial MSM were more likely to visit parks and saunas instead of bars, massage centers, recreational centers, and home-based venues. Syphilis infection and recruitment venue were associated with HIV infection in both MBs and ncMSM. Being from a hometown with a high HIV prevalence and without a male partner from Hong Kong were found to be risk factors for HIV infection in MBs, and early sexual debut was a risk factor in ncMSM. CONCLUSION: Money boys differed from ncMSM in the rate of HIV infection and some sexual characteristics and behaviors. Formatting separate interventions specifically targeting the 2 subgroups may be necessary.

RESUMO

To investigate the association between lead powder use, as folk skin care, and blood lead level (BLL) in children, we studied 222 children up to 14-years old living in a Chinese rural area and administered a face to face interview with their parents to collect information on lead powder use and other potential exposure. We measured children's BLL at baseline and 2 years later after an intervention. The children were divided into three categories according to their use of lead powder: regular use, irregular use and never use. We applied multivariate linear regression to determine the association between lead powder use and elevated BLL. The average BLL of all children was 18 µg/dl; 56% of them had BLL of 10 µg/dl or higher. Lead powder use was significantly associated with elevated BLL. After adjusting for potential confounders the BLL of regular and irregular users was higher than non-users by 3.11 µg/dl and 1.47 µg/dl, respectively. Duration of lead powder use was positively associated with BLL, but the time since last use was inversely associated. A significant BLL reduction was observed 2 years later, and the greatest reduction (21 µg/dl) was seen in the youngest group of regular users. This study showed that traditional use of lead powder for a skin care purpose was a major contributor to elevated BLL in these children.

RESUMO

OBJECTIVE: To develop a measurement of safety climate at workplace and assess its validity and reliability. METHODS: According to the theory of preventive safety culture model, a scale including 7 dimensions of 27 items was developed. 342 workers were selected from among all workers of an artificial board factory and were investigated with the developed scale. Occupational accidents were recorded during the past year. Factor analysis, association validation and inter-item consistency test were applied to assess the scale validity and reliability. RESULTS: After the deletion of 6 items, 21 items composed the safety climate scale, which was loaded on 7 common factors: safety competence and consciousness, safety communication, organizational environment, management support, danger judgment, safety control measure and safety training. The cumulative contribution reached to 70.50%. All item communities (common factor variance) were above 0.6 except one item was 0.595. ANOVA showed that occupational accidents were associated with the safety climate score on total, danger judgment and safety control measure dimension (P < 0.05). There existed significant correlation between the safety climate total score and dimension scores (P < 0.01), the correlation coefficients were 0.700, 0.728, 0.705, 0.703, 0.354, 0.571 and 0.485 respectively. The safety climate scale total Cronbach's alpha coefficient, half-split Spearman-Brown coefficient, theta coefficient and omega coefficient indicated that the safety climate scale had good inter-item consistency among items. CONCLUSION: The measurement of safety climate at workplace is developed. It has good reliability and valid.
