Sexual violence and its health consequences for female children in Swaziland: a cluster survey study

BACKGROUND Despite concern, few studies have been done about sexual violence against girls younger than 18 years of age in sub-Saharan Africa. We report the prevalence and circumstances of sexual violence in girls in Swaziland, and assess the negative health consequences. METHODS We obtained data from a nationally representative sample of girls and women aged 13-24 years from selected households in Swaziland between May 15, 2007, and June 16, 2007, with a two-stage cluster design. The questionnaire examined demographics, type of sexual violence that took place before the respondent was 18 years of age, circumstances of the incident, and health-related conditions. Information was gathered from 1244 women and girls (response rate 96.3%), of whom 1242 provided retrospective responses to questions about sexual violence. We used regression models adjusted for relevant demographics to estimate the odds ratios for the associations between sexual violence and health-related conditions. FINDINGS 33.2% (95% CI 29.9-36.7) of respondents reported an incident of sexual violence before they reached 18 years of age. The most common perpetrators of the first incident were men or boys from the respondents neighbourhood (32.3% [28.8-36.1]) and boyfriends or husbands (26.2% [22.2-30.7]). The first incident most often took place in the respondents own home (26.1% [21.6-31.2]). Sexual violence was associated with reported lifetime experience of sexually transmitted diseases (adjusted OR 3.69 [95% CI 1.78-7.66]), pregnancy complications or miscarriages (3.54 [1.47-8.55]), unwanted pregnancy (2.92 [1.87-4.55]), and self-report of feeling depressed (2.30 [1.70-3.11]). INTERPRETATION Knowledge of the high prevalence of sexual violence against girls in Swaziland and its associated serious health-related conditions and behaviours should be used to develop effective prevention strategies.

Treatment for LTBI in contacts of MDR-TB patients, Federated States of Micronesia, 2009–2012

SETTING Few studies have shown the operational feasibility, safety, tolerability, or outcomes of multidrug-resistant latent tuberculous infection (MDR LTBI) treatment. After two simultaneous multidrug-resistant tuberculosis (MDR-TB) outbreaks in Chuuk, Federated States of Micronesia, infected contacts were offered a 12-month fluoroquinolone (FQ) based MDR LTBI treatment regimen. DESIGN Between January 2009 and February 2012, 119 contacts of MDR-TB patients were followed using a prospective observational study design. After MDR-TB disease was excluded, 12 months of daily FQ-based preventive treatment of MDR LTBI was provided by directly observed therapy. RESULTS Among the 119 infected contacts, 15 refused, while 104 began treatment for MDR LTBI. Of the 104 who initiated treatment, 93 (89%) completed treatment, while 4 contacts discontinued due to adverse effects. None of the 104 contacts who undertook MDR LTBI treatment of any duration developed MDR-TB disease; however, 3 of 15 contacts who refused and 15 unidentified contacts developed MDR-TB disease. CONCLUSION Providing treatment for MDR LTBI can be accomplished in a resource-limited setting, and contributed to preventing MDR-TB disease. The Chuuk TB program implemented treatment of MDR LTBI with an 89% completion rate. The MDR LTBI regimens were safe and well tolerated, and no TB cases occurred among persons treated for MDR LTBI.

Risk factors associated with sexual violence towards girls in Swaziland

OBJECTIVE To explore risk factors for sexual violence in childhood in a nationally representative sample of females aged 13 to 24 years in Swaziland. METHODS During a household survey respondents were asked to report any experiences of sexual violence before the age of 18 years. The association between childhood sexual violence and several potential demographic and social risk factors was explored through bivariate and multivariate logistic regression. FINDINGS Participants totalled 1244. Compared with respondents who had been close to their biological mothers as children, those who had not been close to her had higher odds of having experienced sexual violence (crude odds ratio, COR: 1.89; 95% CI: 1.14-3.14), as did those who had had no relationship with her at all (COR: 1.93; 95% CI: 1.34-2.80). In addition, greater odds of childhood sexual violence were noted among respondents who were not attending school at the time of the survey (COR: 2.26; 95% CI: 1.70-3.01); who were emotionally abused as children (COR: 2.04; 95% CI: 1.50-2.79); and who knew of another child who had been sexually assaulted (COR: 1.77; 95% CI: 1.31-2.40) or was having sex with a teacher (COR: 2.07; 95% CI: 1.59-2.69). Childhood sexual violence was positively associated with the number of people the respondent had lived with at any one time (COR: 1.03; 95% CI: 1.01-1.06). CONCLUSION Inadequate supervision or guidance and an unstable environment put girls at risk of sexual violence. Greater educational opportunities and an improved mother-daughter relationship could help prevent it.

Tuberculosis among the homeless, United States, 1994–2010

OBJECTIVES 1) To describe homeless persons diagnosed with tuberculosis (TB) during the period 1994-2010, and 2) to estimate a TB incidence rate among homeless persons in the United States. METHODS TB cases reported to the National Tuberculosis Surveillance System were analyzed by origin of birth. Incidence rates were calculated using the US Department of Housing and Urban Development homeless population estimates. Analysis of genotyping results identified clustering as a marker for transmission among homeless TB patients. RESULTS Of 270,948 reported TB cases, 16,527 (6%) were homeless. The TB incidence rate among homeless persons ranged from 36 to 47 cases per 100,000 population in 2006-2010. Homeless TB patients had over twice the odds of not completing treatment and of belonging to a genotype cluster. US- and foreign-born homeless TB patients had respectively 8 and 12 times the odds of substance abuse. CONCLUSIONS Compared to the general population, homeless persons had an approximately 10-fold increase in TB incidence, were less likely to complete treatment and more likely to abuse substances. Public health outreach should target homeless populations to reduce the excess burden of TB in this population.

Islands of hope: building local capacity to manage an outbreak of multidrug-resistant tuberculosis in the Pacific.

A single case of multidrug-resistant tuberculosis (MDR-TB) can overwhelm the technical and financial capacity of small TB programs. In May 2008, the island state of Chuuk requested assistance for their first cases of MDR-TB. Second-line drugs and isolation rooms were unavailable, lab capacity was limited, and clinicians lacked experience. Delayed response caused prolonged transmission among household contacts. Several agencies responded with technical assistance and resources. Subsequent evaluations identified 16 additional MDR-TB cases and 124 infected contacts. Within six months, the local TB program gained remarkable capacity to manage MDR-TB cases and contacts, and greatly improve care for all TB patients. The Chuuk outbreak demonstrates the importance of establishing MDR-TB readiness in smaller jurisdictions and maintaining an essential TB control infrastructure.

The impact of post-election violence on HIV and other clinical services and on mental health -- Kenya, 2008

INTRODUCTION In December 2007, civil disruption and violence erupted in Kenya following national elections, displacing 350,000 people and affecting supply chains and services. The Kenyan government and partners were interested in assessing the extent of disruption in essential health services, especially HIV treatment. METHODS A two-stage cluster sampling for patients taking antiretroviral therapy (ART) was implemented ten weeks after elections, March 10-21, 2008, at twelve health facilities providing ART randomly selected in each of the three provinces most affected by post-election disruption-Rift Valley, Nyanza, and Central Provinces. Convenience samples of patients with tuberculosis, hypertension, or diabetes were also interviewed from the same facilities. Finally, a convenience sampling of internally displaced persons (IDPs) in the three provinces was conducted. RESULTS Three hundred thirty-six IDPs in nine camps and 1,294 patients in 35 health facilities were interviewed. Overall, nine percent of patients reported having not returned to their routine health care facility; 9%-25% (overall 16%) reported a temporary inability for themselves or their children to access care at some point during January-February 2008. Less than 15% of patients on long-term therapies for HIV, tuberculosis, diabetes, or hypertension had treatment interruptions compared with 2007. The proportion of tuberculosis patients receiving a ≥45-day supply of medication increased from five percent in November 2007 to 69% in December 2007. HIV testing decreased in January 2008 compared with November 2007 among women in labor wards and among persons tested through voluntary counseling and testing services in Nyanza and Rift Valley Provinces. Patients and their family members witnessed violence, especially in Nyanza and Rift Valley Provinces (54%-59%), but few patients (2.5%-14%, 10% overall) personally experienced violence. More IDPs reported witnessing (80%) or personally experiencing (38%) violence than did patients. About half of patients and three-quarters of IDPs interviewed had anxiety or depression symptoms during the four weeks before the assessment. There was no association among patients between the presence of HIV, tuberculosis, diabetes, and hypertension and the prevalence of anxiety or depression symptoms. CONCLUSION More than 85% of patients in highly affected provinces avoided treatment interruptions; this may be in part related to practitioners anticipating potential disruption and providing patients with medications for an extended period. During periods of similar crisis, anticipating potential limitations on medication access and increased mental health needs could potentially prevent negative health impacts.

Molecular Epidemiology of Mycobacterium tuberculosis in the United States–Affiliated Pacific Islands

The United States–Affiliated Pacific Islands (USAPI) are part of the US National Tuberculosis (TB) Surveillance System and use laboratory services contracted through a cooperative agreement with the Centers for Disease Control and Prevention (CDC). In 2004, the CDC established the National Tuberculosis Genotyping Service, a system to genotype 1 isolate from each culture-confirmed case of TB. To describe the molecular epidemiology of TB in the region, we examined all Mycobacterium tuberculosis isolates submitted for genotyping from January 1, 2004, to December 31, 2008. Over this time period, the USAPI jurisdictions reported 1339 verified TB cases to the National Tuberculosis Surveillance System. Among 419 (31%) reported culture-confirmed TB cases, 352 (84%) had complete genotype results. Routine TB genotyping allowed, for the first time, an exploration of the molecular epidemiology of TB in the USAPI.

Increasing Prevalence of Nontuberculous Mycobacteria in Respiratory Specimens from US-Affiliated Pacific Island Jurisdictions1

Nontuberculous mycobacteria (NTM) respiratory infections represent a growing public health problem in many countries. However, there are limited published epidemiologic studies for the Western Pacific region. We reviewed respiratory specimens submitted to Diagnostic Laboratory Services in Hawaii, USA, for culture of Mycobacterium tuberculosis during August 2007–December 2011 to determine the NTM isolation rate. We observed a statistically significant increase in the rate of specimens with NTM isolated in respiratory culture (adjusted rate ratio per year 1.65, 95% CI 1.54–1.77; p<0.01). In contrast, the number of patients with respiratory cultures positive for M. tuberculosis showed no increase (adjusted rate ratio per year 0.98, 95% CI 0.94–1.01; p = 0.19). A 6-month subset of NTM isolates was identified by using a nucleic acid probe or 16S rRNA sequencing. M. avium complex and M. fortuitum were the most common NTM identified.
