We aimed to assess the feeding pattern and influencing factors within six weeks postpartum on exclusive breastfeeding duration among Chinese mothers. This study was conducted using 2:1 matched case-control study. Cases and controls were matched for maternal age, parity and mode of birth. A total of 210 women were included. Approximately 67.9% of women stopped exclusive breastfeeding within the first six weeks postpartum. Maternal non-exclusive breastfeeding intention, lower maternal educational level, mother-infant skin to skin contact over one hour, unsatisfied breastfeeding self-evaluation and maternal unhealthy condition within the first six weeks were risk factors for ceasing exclusive breastfeeding early.

We conducted an epidemiological study to identify the demographics and pre-operative characteristics of patients undergoing primary anterior cruciate ligament (ACL) reconstruction in a multi-ethnic Asian population. A retrospective study was performed on 696 patients who registered in our ACL reconstruction registry from January 2013 to August 2016. Important inter-ethnic differences were found. Indian patients were significantly older compared to Malay and Chinese patients. Malay and Indian patients were more likely to be male, overweight, and obese compared to Chinese patients. Soccer was the predominant sport involved, although ethnic predominance in specific sports exists. Novel findings from this study include increased prevalence of concomitant chondral injuries in the Chinese population compared to Malays and Indians, and significantly higher rates of concomitant intra-articular injuries in soccer and basketball compared to netball. Identification of these high-risk subgroups would serve useful in guiding the formulation of prevention strategies within our multi-ethnic community. [ABSTRACT FROM AUTHOR]

Background: QR (quick response) codes are a promising tool for health education, however effects of QR code application in providing peri-procedure education to patients with coronary angiography is unclear. Aim/Objective: This study investigated the effect of a QR code-based video education program on anxiety, adherence, and satisfaction in Chinese coronary angiography patients. Material and Methods: This prospective controlled clinical trial included 335 patients undergoing coronary angiography, including 166 patients in the experimental group and 169 patients in the control group. On the day before coronary angiography, patients in the experimental group had access to and could watch an educational video on their smartphones by scanning a QR code for multiple times, while patients in the control group watched the same video on a tablet once only. The primary outcome was anxiety assessed using the Chinese State Anxiety Inventory (C-SAI). Adherence to instructions and patient satisfaction with the information delivery method were also evaluated. Results: The C-SAI scores improved in the experimental group compared to the control group (F = 9.8, P < 0.001) over time. There is a significant difference in the changes of anxiety scores from baseline to pre-procedure (P < 0.001) and post-procedure (P < 0.01) between the two groups. Individuals in the experimental group showed better adherence to instructions on removing dentures and jewelry, and taking medicines before the procedure (P < 0.05), and limb activity, water consumption, and diet after the procedure (P < 0.001). Conclusion: Patient education programs on smartphone that can be accessed multiple times by scanning a QR code can be an effective and convenient approach to reducing anxiety and enhancing adherence to instructions among Chinese coronary angiography patients. Hospitals and clinicians should consider more investments in developing such patient education programs and also help improve ehealth literacy. [ABSTRACT FROM AUTHOR]

Poor phonological development adversely affects language development and interpersonal communication abilities in children with Autism Spectrum Disorders (ASD). However, the characteristics of phonological development in children with ASD who speak Putonghua (the official standard spoken form of modern Mandarin Chinese) remain largely unknown. This study aims to investigate phonological acquisition and development among Putonghua-speaking children with ASD. Data were collected from participants recruited in Shanghai, China. Two experiments were conducted. In experiment I, phonological acquisition was compared between 16 children with ASD aged 3–6 years and 16 age-matched typically developing (TD) children. In experiment II, phonological acquisition was compared between 26 children with ASD over 6 years old and 26 receptive-language-age-matched TD children. Picture naming was applied to measure participants' phonology – the 21 initials, 36 finals and four tones of Putonghua. Paired-samples t-tests and Fisher's exact tests were applied. In experiment I, scores on initials, finals, tones and total phonology of children with ASD aged 3–6 years were significantly lower than those of age-matched TD children. The pronunciation accuracy rates for initials such as/x, th, l/, finals such as/jaʊ, joʊ, wo/ and Tone 3 (the low-rising tone) in the ASD group were significantly lower than in the TD group. In experiment II, there was no significant difference in overall phonological developmental level between children with ASD over 6 years old and receptive-language-age-matched TD children. Phonological development of Putonghua-speaking children with ASD was significantly lower than that of age-matched TD children but closer to that of receptive-language-age-matched TD children. Further, participants with ASD showed atypical development sequences in both initials and finals. [ABSTRACT FROM AUTHOR]

Pregnancy stress could lead to adverse health outcomes for both mother and child. Few studies have explored the effectiveness of stress management strategy among pregnant women. To examine the effectiveness of cognitive-behavioral stress management for pregnant women. Randomized Controlled Trial. 100 pregnant women (at 6–8 week of pregnancy) were selected by convenience sampling. Participants in the control group (N = 50) received routine prenatal examination and health education, while those in the intervention group (N = 50) received cognitive-behavioral stress management. Pregnancy Pressure Scale was measured at baseline and 39th weeks of pregnancy. Pregnancy Pressure Scale score increased in both intervention and control groups. However, the score in the intervention group was significantly lower than those in the control group (p < 0.01). Cognitive-behavioral stress managment can effectively reduce pregnant women's stress levels. Nurses and midwives should conduct cognitive-behavioral stress management to help pregnant women reduce their stress. [ABSTRACT FROM AUTHOR]

Research on women who engage both in drug use and sex work has been limited, as most previous studies have focused on these risk behaviors separately. The current study examines the network properties as well as the demographic and behavioral factors associated with drug use among female sex workers (FSWs) in southern China. We collected survey data (n = 175) in the Hainan province during our 26 months of ethnographic fieldwork in China. Our analyses included Fisher's exact chi-square tests, independent-samples t-tests, Mann-Whitney U, binary logistic regression (LR), as well as ethnographic data analysis. Multivariate analysis showed that women who were younger age, single, more educated, and earning a higher income were more likely to use drugs. Pertaining to network properties, FSWs with a lower percentage of long-term clients (and men) in ego networks were more likely to use drugs; this would imply a mechanism by which drug-using FSWs are more at risk, as the women take a greater number of transient clients. In addition, FSWs who were influential network members (i.e., higher betweenness centrality) and were closely related to other network members (i.e., higher closeness centrality) were more likely to use drugs; this may suggest that drug use is a means of sustaining the high functionality of the workers. Our ethnographic data also showed that club drug use was easily accessible in entertainment venues and was often a means of socialization in FSW communities. Network characteristics correlated to HIV-related risks among FSWs should be further examined in future studies. [ABSTRACT FROM AUTHOR]

Previous literature has suggested high rates of HIV/STIs among Chinese FSWs. However, limited data were available regarding HIV-related risks among Vietnamese FSWs – a rapidly increasing, vulnerable population in southwest China. The current study examined the demographic and behavioral factors associated with the infection rates of HIV, syphilis, and Hepatitis C (HCV) among Vietnamese FSWs in Guangxi, China. We conducted a secondary data analysis of a cumulative sample of 1026 Vietnamese FSWs (aged 14–66) recruited over five years (2010–2014) from 35 National Sentinel Surveillance sites in Guangxi. Analyses included Fisher’s exact chi-square test,t-test, and binary logistic regression. The overall prevalence of HIV, syphilis, and HCV infections among the cross-border women were 3.2%, 6.9%, and 2.6%, respectively. Multivariate analysis showed that greater lengths of sex work and low paying work venues were significant risk factors for HIV infection; for syphilis infection, older age, drug use experience, and forgoing condom use were significant risk factors; for HCV infection, drug use experience was the only significant risk factor. Our findings suggest that elevated HIV-related risks among the Vietnamese FSWs are closely related to their financial disadvantages and that drug use is a prominent risk factor for cross-border women in the sex trade. Furthermore, culturally tailored and linguistically accessible HIV prevention and intervention initiatives that target cross-border FSWs, with a close international collaboration between China and Vietnam, are urgently needed.

ConclusionThe Th17 cell frequency in peripheral blood and levels of IL-17 showed significant differences between patients with laryngeal squamous cell carcinoma and those with vocal cords polyps. Serum levels of IL-17 were correlated with laryngocarcinoma staging.ObjectivesTo investigate associations among the frequency of Th17 cells, levels of IL-17, and laryngeal squamous cell carcinoma.MethodEighty in-patients with laryngeal squamous cell carcinoma and 114 in-patients with polypus of the vocal cord were enrolled. Th17 cell frequencies in peripheral blood and serum levels of IL-17 were measured by flow cytometry and enzyme-linked immunosorbent assay, respectively. The tissue expression levels of IL-17 mRNA transcripts and protein were measured using quantitative RT-PCR or immunohistochemical detection, respectively.ResultsTh17 cell frequencies in peripheral blood and serum concentrations of IL-17 were significantly higher in patients with laryngocarcinoma compared with those in patients with polyps (p < 0.01 for both Th17 cells and IL-17 levels). Serum concentrations of IL-17 were significantly higher in patients with advanced laryngocarcinoma than in patients with early laryngocarcinoma (p < 0.01). The mRNA and protein levels of IL-17 were significantly higher in laryngocarcinoma tissues than in adjacent normal tissues (p < 0.01 for mRNA levels,p < 0.05 for protein levels).

Objective: The aim of this study was to analyse the shunt placement in patients who had normal pressure hydrocephalus after poor-grade aneurysmal subarachnoid haemorrhage (aSAH). Methods: Patients diagnosed with NPH after poor-grade aSAH were divided into a treatment group and control group, based on whether they had received ventriculoperitoneal shunt placement. The treatment group was then divided into an improvement group and non-improvement group according to their recovery. The Glasgow Outcome Scale and Mini Mental Scale Examination were used for 3 month and 1 year follow-up rehabilitation measures. Results: Of the 46 total patients, significant improvement was observed at the 3 month and 1 year follow-ups (p < 0.01) after shunt implantation in the treatment group compared to the control group. Furthermore, patients who were younger (p = 0.022), had better neurological function (higher Glasgow Coma Score,p < 0.01) and less severe hydrocephalus (lower EI,p < 0.01) appears to be more likely to benefit from the shunt. Conclusions: Patients who had NPH due to poor-grade aSAH would benefit from shunt placement when given the correct candidates and timely management of shunt malfunction. Additionally, the curative effect of the shunt should have been regarded as a long-term goal of rehabilitation in these patients. [ABSTRACT FROM AUTHOR]

Previous studies suggest that the implementation of universal precaution (UP) plays a role in reducing HIV stigma. In this study we investigate the efficacy of a stigma reduction intervention on UP compliance and explore whether UP compliance could potentially influence HIV stigma reduction in medical settings. A randomized controlled intervention trial was conducted in two provinces of China with 1760 healthcare service providers recruited from 40 county-level hospitals. Longitudinal analyses included data collection at baseline, 6-, and 12-month follow-up assessments. Using a hierarchical modeling approach, we estimated the intervention effect for each provider's UP compliance and its potential mediating role on HIV stigma with the bootstrapping method. A significant intervention effect on UP compliance was observed at both the 6- and 12-month follow-up assessments. The intervention effect on provider avoidance intent was partially mediated by the provider's own UP compliance at the two follow-up points. This study provides evidence that UP compliance should be part of HIV stigma reduction programs, especially in resource-restrained countries. Findings suggest that a protected work environment may be necessary but not sufficient to address HIV stigma in medical settings. [ABSTRACT FROM AUTHOR]

Objectives:To investigate the relationship between glycated albumin (GA) to glycated hemoglobin (HbA1c) ratio and cognitive impairment in old age. Diabetes is associated with cognitive impairment in older people. However, the link between elevated GA/HbA1c levels and the risk of cognitive impairment in nondiabetic individuals is unclear. Methods:A cross-sectional study of 474 old, nondiabetic adults (192 women, mean age 73.8 years ± 6.9 SD) who had been admitted to our hospital was conducted. Glycemic measures included fasting plasma glucose (FPG), 2-hour post-prandial plasmic glucose (2hPPG), GA and HbA1c. Cognitive function was assessed using Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) at the same examination visit in which the glycemic measures were determined. Results:When the individuals were divided into two groups according to the median of GA/HbA1c ratio, old adults with GA/HbA1c ratio ≥ 2.53 showed lower MMSE and MoCA scores compared to those with GA/HbA1c ratio < 2.53. Univariate regression analysis showed that MMSE and MoCA scores were not correlated with HbA1c, but were inversely correlated with GA and GA/HbA1c ratio. Linear regression analysis revealed that there was a significant negative correlation between GA/HbA1c and cognitive function (β = −0.77,P< 0.01 for MoCA and β = −0.69,P< 0.05 for MMSE) even after adjustment for age, body mass index, systolic blood pressure, lipoprotein(a) and sex. Conclusion:Our results indicate that even in the absence of manifest type 2 diabetes mellitus, GA/HbA1c ratio levels exert a negative influence on cognition and it may be a better predictor for cognitive impairment in the older population.

Objective: Subdural hygroma (SDG) is a common complication that can occur after head trauma or secondary to decompressive craniectomy (DC). SDGs can be located not only ipsilateral or contralateral to the side of the DC, but also bilateral or unilateral in patients without DC. This study investigated the incidence and risk factors for different types of SDG in a large cohort of patients with traumatic brain injury (TBI). Methods: A retrospective study was conducted involving 379 adult patients with TBI who were admitted to Huashan Hospital, Fudan University between January 2009 and December 2013. As the outcome was dichotomous (SDG vs no SDG or hydrocephalus vs no hydrocephalus), multivariate logistic regression analyses were used to identify independent risk factors for the development of SDGs in patients without DC, ipsilateral SDG after unilateral DC, contralateral SDG after unilateral DC or SDG after bilateral DC. Risk factors for the development of hydrocephalus were also evaluated in patients with and without DC. Results: Among the 207 (54.6%) patients without DC, 30 (14.5%) had unilateral SDGs and 34 (16.4%) had bilateral SDGs. Of the 172 patients (45.4%) with DC, 134 (77.9%) underwent unilateral DC and 38 (22.1%) underwent bilateral DC. Of the 134 patients who underwent unilateral DC, 49 developed SDG, including 22 (16.4%) ipsilateral SDG, 19 (14.2%) contralateral SDG and eight (6.0%) both ipsilateral and contralateral SDGs. For patients undergoing bilateral DC, 13 (34.2%) developed a SDG. No significant difference in the incidence of SDG was observed between the patients with and without DC (36.0% vs 30.9%, p = 0.291), but the characteristics of SDGs were different between the two groups. Logistic regression analysis showed that factors independently associated with the development of SDG were male sex (odds ratio [OR] = 3.861; 95% CI = 1.642-9.091; p = 0.002), older age (OR = 1.046; 95% CI = 1.021-1.070; p < 0.001), basal cistern haemorrhage (OR = 4.608; 95% CI = 1.510-14.064; p = 0.007), diffuse injury and swelling (OR = 3.158; 95% CI = 1.341-7.435; p = 0.008) or diffuse injury and shift (OR = 3.826; 95% CI = 1.141-12.830; p = 0.030) in patients without DC. Temporal haematoma or contusion in the non-DC side (OR = 2.623; 95% CI = 1.070-6.428; p = 0.035) and traumatic SAH (OR = 3.751; 95% CI = 1.047-13.438; p = 0.042) were independently associated with the development of ipsilateral SDG in patients who underwent unilateral DC. However, factors independently associated with the development of contralateral SDG were frontal haematoma or contusion on the non-DC side (OR = 3.145; 95% CI = 1.272-7.774; p = 0.013) and SDH on the non-DC side (OR = 7.024; 95% CI = 1.477-33.390; p = 0.014). Only craniectomy area (OR = 1.030; 95% CI = 1.008-1.052; p = 0.008) was independently associated with the development of SDG in patients with bilateral DC. In the multivariate analysis, SDG in patients without DC was not associated with the development of hydrocephalus. However, SDG was significantly associated with the development of hydrocephalus for patients who underwent DC (OR = 2.173; 95% CI = 1.362-3.467; p = 0.001). Conclusions: This study suggested that the incidence of SDG in patients who have and have not undergone DC was identical; however, the patients' characteristics and risk factors differed. Therefore, the management and prediction of SDG should be performed according to SDG type. [ABSTRACT FROM AUTHOR]

Conclusions: Immunoglobulin (Ig) M is overexpressed in laryngeal squamous cell carcinoma (LSCC), and its expression has an independent protective impact on disease-free survival in LSCC. Objective: A number of studies have reported on the ectopic expression of Ig in cancer cells, yet there has been a lack of understanding of its clinical and prognostic significance. This study aimed to investigate the expression of IgM in resected specimens of LSCC and to evaluate its clinical significance and prognostic value. Methods: Immunohistochemistry (IHC) and Western blotting were used to detect the expression of IgM in LSCC and normal laryngeal tissues. The serum level of IgM was also analyzed by immunoturbidimetric assay. Results: IHC and Western blot studies demonstrated that IgM was overexpressed in LSCC specimens ( p < 0.001), while the serum level of IgM in patients with LSCC was not different from healthy controls. Chi-squared analysis revealed that the expression level of IgM was negatively correlated with regional lymph node metastasis and tumor stage ( p = 0.011 and 0.025, respectively). Univariate analysis showed that IgM expression was significantly correlated with enhanced disease-free survival (DFS) ( p = 0.004). In multivariate analysis, IgM retained its independent prognostic value for DFS ( p = 0.048, HR = 0.506, 95% CI = 0.257-0.995). [ABSTRACT FROM AUTHOR]

Conclusion: rAAV-NT4-ADNF-9 could ameliorate the damage to auditory function and repair previous impairment of cochlear hair cell loss induced by kanamycin. Objective: To investigate the therapeutic effect of ADNF-9 on cochlear hair cells using the recombinant adeno-associated virus (AAV) carrying fusion gene NT4-ADNF-9 and the kanamycin-deafened guinea pig model. Methods: Forty white guinea pigs with normal auricle reflex and normal auditory brainstem responses (ABRs) were randomly divided into four groups. Kanamycin was administered to the animals in groups A, B, and C to establish the deafened guinea pig model. rAAV-NT4-ADNF-9, vector only, and artificial perilymph were then delivered to the cochlear tissue of animals in groups A, B, and C, respectively, through the round window membrane. Animals in group D did not receive any treatment and acted as normal controls. The hearing thresholds on the surgery side were recorded before and after the transfection treatment. Fourteen days after treatment, cochleae were removed for paraffin slide preparation and cochlear surface preparation. A phase contrast microscope was used to observe the protective effect of ADNF-9 on hair cells. Results: Significant reduction of the ABR threshold was observed after rAAV-NT4-ADNF-9 treatment ( p < 0.05). After 14 days of treatment, the ABR threshold was also significantly different between the rAAV-NT4-ADNF-9-infected group and the non-infected group. Moreover, phase contrast microscopy showed significantly less hair cell damage or hair cell loss in the group treated with rAAV-NT4-ADNF-9 than in the groups treated with vector only or artificial perilymph ( p < 0.05).

To determine the level of antiretroviral treatment adherence and explore the correlated factors of perceived burden of taking antiretroviral medications among people living with HIV (PLH) in a rural area of China. Data were collected from 66 PLH who were currently receiving antiretroviral treatment. Face-to-face interviews were conducted during August to October, 2009. Approximately 18.2% of participants failed to adhere to antiretroviral treatment in the previous 30 days. A majority of PLH reported that taking antiretroviral medications posed a burden to them. Those who perceived a higher level of burden were more likely to be women, to have lower annual income, and to report a high level of depressive symptoms, poor physical health, and strained family interactions. Findings suggest that future programs in promoting adherence to antiretroviral treatment should address issues related to psychosocial well-being and PLH's interactions with their family members.

Background: Invasive mold infection (IMI) is a major cause of infection-related mortality following allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: We retrospectively analyzed 190 allo-HSCT recipients at Changhai Hospital between the y 2000 and 2007. The survival rate was evaluated with Kaplan-Meier curves. Logistic and Cox regression models were used for multivariate analyses. Results: The 1st y cumulative incidence rate of IMI was 12.8%, and invasive aspergillosis was the most commonly observed IMI (85%). Multivariate logistic regression analyses showed that significant predictors of IMI were corticosteroid therapy (odds ratio (OR) 1.656, 95% confidence interval (CI) 1.047-2.621, p == 0.031), positive cytomegalovirus antigenemia (OR 5.301, 95% CI 1.902-14.772, p == 0.001), and secondary neutropenia (OR 5.250, 95% CI 1.741-15.834, p == 0.003). The mortality rate of IMI at 12 weeks after diagnosis was 60%. In Cox regression models, IMI-related mortality was related to the dose of corticosteroid (2 mg/kg/day or more) administered at the time of IMI diagnosis (hazards ratio (HR) 20.841, 95% CI 2.151-201.944, p == 0.009) and neutropenia (HR 7.043, 95% CI 1.186-41.827, p == 0.032). Conclusions: These data confirm previous findings that the incidence and mortality of IMI are mostly associated with immunodeficiency caused by immunosuppressive therapy or virus infection.

Background: Hemorrhagic fever with renal syndrome (HFRS) is a serious public health problem in China, and is primarily caused by either the Hantaan virus (HTNV) or Seoul virus (SEOV) strains. However, the causative hantavirus has only been definitively identified in a few HFRS cases, and detailed comparisons of patient data for the 2 strains are limited. Methods: We conducted a 1-y prospective study in Heilongjiang Province, China. A total of 152 patients from 3 hospitals met the HFRS diagnostic criteria used in China. The diagnosis was further confirmed by specific immunoglobulin M to HTNV or SEOV. In addition, serum samples were tested for the presence of HTNV or SEOV using a reverse transcription-polymerase chain reaction (RT-PCR). Clinical manifestations and laboratory findings in patients with the 2 hantaviruses were subsequently compared. Results: Eighty (61.1%) HTNV and 51 (38.9%) SEOV infections were identified. Fever and proteinuria, key to the diagnosis of HFRS, were observed in all patients. The clinical manifestations of hemorrhage and renal injury from SEOV infection were milder than those of HTNV infection. Interestingly, compared to patients with HTNV infection, patients with SEOV presented with a significantly longer febrile period, more normal white blood cell counts or even transient leukocytopenia, a higher incidence of liver injury related to disease severity, and a lower occurrence of the 5 typical phases of HFRS. The mortality was 6.3% in HTNV infections and 0% in SEOV infections. Conclusions: Clinical manifestations of SEOV infection appear to be milder and less typical than HTNV. This information may help us to improve the diagnosis of SEOV-infected patients. [ABSTRACT FROM AUTHOR]

Men who have sex with men (MSM) are of immediate concern in China's HIV epidemic. In 2008, approximately 2.5-6.5% of China's eight million MSM were HIV positive, while MSM represented 11% of all new HIV cases. Two factors that will in-part determine HIV-transmission dynamics among MSM, are sexual mixing patterns and the social networks which shape them. Sexual mixing patterns and social networks of Chinese MSM, however, remain poorly understood with little refined data available. One reason is that stigma discourages disclosure of names and identifiers to researchers. Using an alternative network-mapping approach, matched case-control design, and snowball sampling, this pilot study sought to compare characteristics of social networks of HIV-positive and HIV-negative Beijing MSM at the individual, dyad, and network levels. First, HIV-negative MSM controls were matched to HIV-positive MSM cases based on age, education, residency, and ethnicity. Then, each case or control and their MSM social network convened at a specific time and location with study investigators. Venues included health clinics, karaoke clubs, brothels, and community centers. Then, using arbitrarily assigned numbers in lieu of actual names, all participants simultaneously completed self-administered surveys regarding their sexual relationships with other participants of the same social network. These new findings indicate that cross-generational sex (anal or oral sex between men with ≥10 years age difference) was more prevalent among social networks of HIV-positive MSM, and was due to older age structure of the social network, rather than behavioral differences in sex-partner selection. Members of social networks of HIV-positive MSM were also less likely to have ever disclosed their MSM identity to non-MSM. Future studies should partner with MSM advocacy groups to explore behavioral and structural interventions as possible means of reducing the cross-generational sex and sexual identity-development issues elevating HIV risk for young Chinese MSM.

The objective of our study was to understand the trend of AIDS deaths and the impact of AIDS-related deaths on the local mortality rate in seven villages in Shangcai County, Henan Province. A retrospective study survey among all deaths was conducted through household visits from 1 January 1995 to 31 October 2007 in seven administrative villages in Shangcai County of Henan Province. The cause of death and characteristics of the deceased were analyzed. There were a total of 2546 deaths, of which 521 (20.5%) were HIV/AIDS-related, 525 (20.6%) were suspected AIDS deaths, and 1500 (58.9%) were unrelated HIV/AIDS deaths. The proportion of deaths among people aged 20-49 years was less than 20% from 1995 to 1997, but increased to 27.4% in 1998, and reached 49.2% in 2001, followed by a decrease in succeeding years, dropping to 29.5% in 2007. HIV/AIDS-related and suspected deaths among those aged 20-49 years accounted for 63.9% and 70.9% of all deaths, respectively. The overall mortality rate was 7‰ from 1995 to 1999, and 14.9‰ in 2002. Our study shows that confirmed HIV/AIDS-related deaths and suspected AIDS deaths were the main cause of deaths at the local level after 1998, especially among those aged 20-49. [ABSTRACT FROM AUTHOR]
