ABSTRACT

AIM: To investigate the morbidity of functional bowel disorders (FBD) under military stress conditions in order to lay foundations for the prevention and treatment of this disease. METHODS: Four hundred and fifty-seven soldiers who were assigned to specified services and 471 soldiers who were assigned to routine services were enrolled using cluster sampling, with the latter as a control group. They were surveyed using the Rome III FBD standard questionnaire. The FBD symptom questionnaire included FBD-related symptoms, severity, duration or attack time, and accompanying symptoms. RESULTS: The morbidity of the military stress group (14.6%) was significantly higher than in the control group (9.98%) (χ² = 4.585, P < 0.05). The incidence of smoking, abdominal pain and acid regurgitation (χ² = 4.761, P < 0.05) as well as the ZUNG anxiety/depression scores (χ² = 7.982, P < 0.01) were also significantly higher in the military stress group compared with the control group. ZUNG anxiety (χ² = 11.523, P < 0.01) and depression (χ² = 5.149, P < 0.05) scores were higher in the FBD group compared with the non-FBD group. The differences in the ZUNG self-rated anxiety and depression scales between the 2 groups were statistically significant (χ² = 14.482, P < 0.01 and χ² = 6.176, P < 0.05). CONCLUSION: The morbidity of FBD was higher under military stress conditions.

ABSTRACT

Objective To study the HIV incidence and risk factors among sero-negative spouses of HIV patients in Dehong prefecture of Yunnan province. Methods A cohort of sero-negative spouses of the HIV patients had been developed and followed up since November, 2005.HIV new infections and related behaviors had been investigated every six months. Results By the end of June, 2008, 790 sero-negative spouses of HIV patients had been recruited, of whom 702 were followed-up for at least one time. During the total 1202.35 person-years, 31 new HIV infections were identified, with an overall incidence of 2.58/100 preson-years. The HIV incidence rates were 2.22/100person-years in 2006, 2.95/100 person-years in 2007 and 2.74/100 person-years in 2008. Data from the Cox proportional hazard regression model indicated that those who resided in Yingjiang county [hazard ratio (HR) =4.37, 95% CI: 1.48-12.90, P=0.008] , ever using drugs (HR=3.49, 95% CI:1.09-11.18, P=0.035) , or having an HIV-infected spouse who never exposed to antiretroviraltreatment (HR=3.60, 95% CI: 1.41-9.16, P=0.007) were at higher risk for HIV infection.Conclusion Sero-negative spouses of HIV patients in Dehong prefecture of Yunnan province had a relatively high incidence of HIV new infection during 2006-2008. More efforts should put on those people living in these areas, having a history of drug use or having an HIV-infected spouse who had never been exposed to antiretroviral treatment.

ABSTRACT

<p><b>OBJECTIVE</b>To determine the incidence and risk factors on HIV infection among injection drug users (IDU) in Dehong prefecture area of Yunnan province.</p><p><b>METHODS</b>An epidemiological cohort of HIV-negative IDU had been developed and followed since October, 2004. HIV new infections and related behaviors had been investigated every six months.</p><p><b>RESULTS</b>By the end of 2008, 760 HIV-negative IDU had been recruited and followed for a total of 1153.6 person-years. 47 new HIV infections were identified, with an overall incidence of 4.07/100 person-years during the follow-up period. The HIV incidence was 4.45/100 person-years during 2004 - 2006, 4.50/100 person-years in 2007 and 2.54/100 person-years in 2008. Both the behavior of drug injection and the HIV incidence among the cohort had substantially decreased during the follow-up period. Multiple regression analysis using Cox proportional hazard model indicated that people with Jing-po ethnicity (Hazard ratio, HR = 2.56, 95%CI: 1.06 - 6.19) and other minorities except for Dai (HR = 3.26, 95%CI: 0.89 - 11.96) were at higher risk for HIV infection than the people with Han ethnicity. People injecting drugs with (HR = 2.27, 95%CI: 0.98 - 5.25) or without (HR = 5.27, 95%CI: 2.25 - 12.34) needle sharing were at higher risk for HIV infection than those reporting having no drug injection behavior during the follow-up period.</p><p><b>CONCLUSION</b>Both the behavior of drug injection and the HIV incidence among former IDU in Dehong prefecture area of Yunnan province had been decreasing during the four years. However, needle sharing remained the most important risk factor for HIV new infection among IDUs. IDUs with different ethnicities seemed to have different risks towards HIV infection.</p>
