Perceptions of service providers, service recipients and female community health volunteers on a rural obstetric ultrasound program in rural Nepal: a qualitative study.

BACKGROUND: In rural Nepal, where women face financial and geographic barriers in accessing ultrasound scans, the government initiated a Rural Obstetric Ultrasound Program (ROUSG) to train skilled birth attendants (SBAs) in rural birthing centers and expand access to routine ultrasound scans for local pregnant women. This study explores the perceived benefits and limitations of the training and implementation of this program. METHODS: A qualitative study was conducted in 15 primary care facilities in Bhojpur and Dhading, two rural districts of Nepal. The research team conducted in-depth interviews with 15 trained SBAs and focus group discussions with 48 service recipients and 30 FCHVs to gain insight into their perceptions. All interviews and focus group discussions were recorded, reviewed, and manually coded into MS Excel. RESULTS: Overall, our findings indicated that the ROUSG program was very well received among all our study participants, though critical gaps were identified, mostly during the training of the SBAs. These included insufficient guidance or practice opportunities during training and the challenges of implementing the mobile obstetric ultrasound service. Most importantly, though, our results suggest that the implementation of the ROUSG program increased access to prenatal care, earlier identification and referrals for abnormal scans, as well as reduced pregnancy-related stress. There was also a notable anecdotal increase in antenatal care utilization and institutional deliveries, as well as high satisfaction in both service providers and recipients. CONCLUSION: Our findings highlighted that while the training component could use some strengthening with increased opportunities for supervised practice sessions and periodic refresher training after the initial 21-days, the program itself had the potential to fill crucial gaps in maternal and newborn care in rural Nepal, by expanding access not only to ROUSG services but also to other MNH services such as ANC and institutional deliveries. Our findings also support the use of ultrasound in areas with limited resources as a solution to identify potential complications at earlier stages of pregnancy and improve timely referrals, indicating the potential for reducing maternal and neonatal morbidities. This initial study supports further research into the role ROUSG can play in expanding critical MNH services in underserved areas and improving broader health outcomes through earlier identification of potential obstetric complications.

Socio-culturally adapted educational videos increase maternal and newborn health knowledge in pregnant women and female community health volunteers in Nepal's Khotang district.

OBJECTIVES: While Nepal has made significant improvements in maternal and newborn health overall, the lack of maternal and newborn health-related knowledge in the more rural parts of the country has led to significant disparities in terms of both maternal and newborn health service utilization and maternal and newborn health outcomes. This study aimed to assess whether viewing culturally adapted maternal and newborn health educational films had a positive impact on (1) the maternal and newborn health knowledge levels among pregnant women and (2) the postpartum hemorrhage-related knowledge levels among Female Community Health Volunteers in rural Nepal. METHODS: Four locations were selected for their remoteness and comparatively high number of pregnancies. A convenience sample of 101 pregnant women and 39 Female Community Health Volunteers were enrolled in the study. A pre- and post-test design was employed to assess this intervention. Paired t-tests were used to analyze the change in number of correct responses by knowledge domain for multi-film participants, producing a numeric "mean knowledge score," and McNemar's tests were used to calculate the change and significance among select questions grouped into distinct themes, domains, and points of "maternal and newborn health-related knowledge" based on the priorities outlined in Nepal's maternal and newborn health 2030 goals. RESULTS: There was a significant improvement in knowledge scores on maternal and newborn health issues after watching the educational films for both types of participants. The mean knowledge score for pregnant women improved from 10 to 15 (P < 0.001) for the Understanding Antenatal Care (ANC) film, 3 to 10 (P < 0.001) for the Warning Sign in Pregnancy film, and 6 to 14 (P < 0.001) for the Newborn Care film. For the Female Community Health Volunteers, knowledge also significantly improved (P < 0.05) in all except one category after watching the postpartum hemorrhage film. The percent that correctly answered when to administer misoprostol (80%-95%) was the only variable in which knowledge improvement was not significant (P < 0.057). CONCLUSION: Using culturally adapted educational films is an effective intervention to improve short-term maternal and newborn health-related knowledge among rural populations with low educational levels. The authors recommend additional larger-scale trials of this type of intervention in Nepal and other low- and middle-income countries to determine the impact on long-term maternal and newborn health knowledge and behaviors among rural populations.

Effect of single session counselling on partner referral for sexually transmitted infections management in Bangladesh.

OBJECTIVES: This study evaluated the role of single session counselling on partner referral among index cases diagnosed as having sexually transmitted infections (STIs) in Bangladesh. METHODS: A quasirandomised trial was conducted in 1339 index cases with symptomatic STIs in 3 public and 3 non-government organisation operated clinics. RESULTS: Out of 1339 index cases, partner referral was achieved by 37% in the counselling group and 27% in the non-counselling group. Index cases in the counselling group and non-counselling group were similar in terms of condom use rates, STI symptoms and duration of disease. A quarter of the index cases reported having more than one sex partner in last 3 months, and 39% reported having commercial sex partners. Only 8% of the index cases reported using condoms during their last sex act. Partner referral rates were higher among index clients with higher age, higher income, those who attended NGO clinics, those who had only one partner and among those who had no commercial partners, but counselling had significantly positive impact in all of these subgroups. In multivariate analysis, the probability of partner referral was 1.3 times higher among index cases in the counselling group (prevalence ratio 1.3; 95% CI 1.1 to 1.6) as compared to index cases in the non-counselling group. CONCLUSIONS: Patient-oriented single session counselling was found to have a modest but significant effect in increasing partner referral for STIs in Bangladesh, greater emphasis should be placed on examining further development and dissemination of partner referral counselling in STI care facilities.

Randomized controlled trial to improve childhood immunization adherence in rural Pakistan: redesigned immunization card and maternal education.

OBJECTIVE: A substantial dropout from the first dose of diphtheria-tetanus-pertussis (DTP1) to the 3rd dose of DTP (DTP3) immunization has been recorded in Pakistan. We conducted a randomized controlled trial to assess the effects of providing a substantially redesigned immunization card, centre-based education, or both interventions together on DTP3 completion at six rural expanded programme on immunization (EPI) centres in Pakistan. METHODS: Mother-child pairs were enrolled at DTP1 and randomized to four study groups: redesigned card, centre-based education, combined intervention and standard care. Each child was followed up for 90 days to record the dates of DTP2 and DTP3 visits. The study outcome was DTP3 completion by the end of follow-up period in each study group. RESULTS: We enrolled 378 mother-child pairs in redesigned card group, 376 in centre-based education group, 374 in combined intervention group and 378 in standard care group. By the end of follow-up, 39% of children in standard care group completed DTP3. Compared to this, a significantly higher proportion of children completed DTP3 in redesigned card group (66%) (crude risk ratio [RR] = 1.7; 95% CI = 1.5, 2.0), centre-based education group (61%) (RR = 1.5; 95% CI = 1.3, 1.8) and combined intervention group (67%) (RR = 1.7; 95% CI = 1.4, 2.0). CONCLUSIONS: Improved immunization card alone, education to mothers alone, or both together were all effective in increasing follow-up immunization visits. The study underscores the potential of study interventions' public health impact and necessitates their evaluation for complete EPI schedule at a large scale in the EPI system.

Sexual mixing patterns among social networks of HIV-positive and HIV-negative Beijing men who have sex with men: a multilevel comparison using roundtable network mapping.

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.

Association between tobacco use in pregnancy and placenta-associated syndromes: a population-based study.

INTRODUCTION: Cigarette smoking is an established risk factor for adverse perinatal outcomes. The purpose of this study is to examine the association between maternal smoking in pregnancy and the occurrence of placental-associated syndromes (PAS). METHODS: We analyzed data from a population-based retrospective cohort of singleton deliveries that occurred in the state of Missouri from 1989 through 2005 (N = 1,224,133). The main outcome was PAS, a composite outcome defined as the occurrence of placental abruption, placenta previa, preeclampsia, small for gestational age, preterm or stillbirth. We used logistic regression models to generate adjusted odd ratios and their 95 percent confidence intervals. Non-smoking gravidas served as the referent category. RESULTS: The overall prevalence of prenatal smoking was 19.6%. Cigarette smoking in pregnancy was associated with the composite outcome of placental syndromes (odds ratio, 95% confidence interval = 1.59, 1.57-1.60). This association showed a dose-response relationship, with the risk of PAS increasing with increased quantity of cigarettes smoked. Similar results were observed between smoking in pregnancy and independent risks for abruption, previa, SGA, stillbirth, and preterm delivery. CONCLUSION: Maternal smoking in pregnancy is a risk factor for the development of placenta-associated syndrome. Smoking cessation interventions in pregnancy should continue to be encouraged in all maternity care settings.

Prevalence of syphilis among antenatal clinic attendees in Karachi: imperative to begin universal screening in Pakistan.

OBJECTIVES: To assess the prevalence and associated risk factors of syphilis among antenatal clinic attendees by a multi-center cross-sectional study in Karachi, Pakistan. METHODS: We administered a structured questionnaire and obtained a blood sample for syphilis serology (rapid plasma reagin test with Treponema pallidum hemagglutination assay confirmation) from all women giving informed consent over six weeks in 2007. Prevalence was calculated at 95% confidence intervals. Multivariate analysis was adapted to assess risk factors. RESULTS: There were seven (0.9%) confirmed cases of syphilis (95% CI: 0.4, 1.8) in a sample size of 800 women recruited from three urban sites (-1% refusal rate). Women who lived in an area where male drug use is prevalent had 1.5% higher prevalence rates than women from the other two sites 0.5%. CONCLUSIONS: We documented higher-than-expected syphilis seroprevalence rates in a low risk population of antenatal clinic attendees in Pakistan. Bridge populations for syphilis may include drug users, who are usually married, and Hijras or their clients. In accordance with our results, the national policy for syphilis control in Pakistan should be modified to include universal syphilis screening in antenatal clinics with subsequent partner notification.

Determinants of third dose of diphtheria-tetanus-pertussis (DTP) completion among children who received DTP1 at rural immunization centres in Pakistan: a cohort study.

OBJECTIVE: In Pakistan, a high proportion of children fail to complete third dose of diphtheria-tetanus-pertussis (DTP3) after having received the first dose (DTP1). A cohort study was conducted to identify the factors predicting three doses of diphtheria-tetanus-pertussis (DTP3) completion among children who have received DTP1 at six centres of Expanded Programme on Immunization (EPI) in rural Pakistan. METHOD: We analyzed a cohort of mother-child pairs enrolled at DTP1 between November 2005 and May 2006 in the standard care group of a larger randomized controlled trial. Data were collected from mothers on a structured questionnaire at enrollment, and each child was followed up at clinic visits for 90 days to record dates of DTP2 and DTP3. Multivariable log-binomial regression analysis was performed to identify the independent predictors of DTP3 completion. RESULTS: Only 39% (149/378) of enrolled children completed DTP3 during the follow-up period. After adjusting for the centre of enrollment in multivariable analysis, DTP3 completion was higher among children who were < or =60 days old at enrolment [adjusted risk ratio (Adj. RR) 1.39, 95% confidence interval (CI): 1.06-1.82], who were living in a household with monthly household income >Rs. 3000 (US$ 50) (Adj. RR 1.76, 95% CI: 1.16-2.65), and who were living < or =10 min away from EPI centre (Adj. RR 1.31, 95% CI: 1.04-1.66). CONCLUSIONS: Interventions targeting childhood immunization dropouts should focus on bringing more children to EPI centres on-time for initial immunization. Relocation of existing EPI centres and creation of new EPI centres at appropriate locations may decrease the travel time to the EPI centres and result in fewer immunization dropouts.

Are treatments for cervical precancerous lesions in less-developed countries safe enough to promote scaling-up of cervical screening programs? A systematic review.

BACKGROUND: Since the mid-1990 s, there have been growing efforts to prevent cervical cancer in less-developed countries through the development of innovative screening approaches such as visual inspection of the cervix associated with same day management of cervical lesions with cryotherapy or loop electrosurgical excision procedure (LEEP). In the past, promising cancer screening interventions have been widely promoted despite incomplete evidence, only to become the subject of intense controversies about ensuing net health benefit. Because the efficacy and effectiveness of the new protocols for global cervical cancer screening have not been well characterized yet, and as a contribution to the evaluation of the balance between the benefits and risks of these protocols, we reviewed the literature on the safety of cryotherapy and LEEP for cervical intraepithelial neoplasia (CIN) in low- and middle-income countries. METHODS: We searched 12 databases (Medline, Google Scholar, Scopus, Cochrane Library, Web of Science, OCLC, PAIS International Database, WHO Global Health Library, CINAHL, Science.gov, NYAM Grey Literature Report, and POPLINE) for original research published between January 1995 and April 2009. Both peer-reviewed publications and items of "grey" literature were retrieved; no language restriction was applied. We calculated the median (minimum, maximum) reported rate for each harm considered. Because of limitations and heterogeneity in the data, no formal meta-analysis was performed. RESULTS: The search identified 32 articles that reported safety data from 24 cryotherapy and LEEP studies. The combined sample consisted of 6,902 women treated by cryotherapy and 4,524 women treated by LEEP. Most studies were conducted in reference or research settings in Asia and Africa. Short-term harms of cryotherapy and LEEP appeared to be similar to those described in the literature from high-income countries. Information was sparse on HIV-related harms and long-term reproductive outcomes of treatment. CONCLUSIONS: When performed in resource-limited settings by qualified providers, cryotherapy and LEEP are not associated with excess harm. However, available data are insufficient to propose fully evidence-based protocols for routine screening of HIV-infected women and women of reproductive age.

Partner notification for sexually transmitted infections in developing countries: a systematic review.

BACKGROUND: The feasibility and acceptability of partner notification (PN) for sexually transmitted infections (STIs) in developing countries was assessed through a comprehensive literature review, to help identify future intervention needs. METHODS: The Medline, Embase, and Google Scholar databases were searched to identify studies published between January 1995 and December 2007 on STI PN in developing countries. A systematic review of the research extracted information on: (1) willingness of index patients to notify partners; (2) the proportion of partners notified or referred; (3) client-reported barriers in notifying partners; (4) infrastructure barriers in notifying partners; and (5) PN approaches that were evaluated in developing countries. RESULTS: Out of 609 screened articles, 39 met our criteria. PN outcome varied widely and was implemented more often for spousal partners than for casual or commercial partners. Reported barriers included sociocultural factors such as stigma, fear of abuse for having an STI, and infrastructural factors related to the limited number of STD clinics, and trained providers and reliable diagnostic methods. Client-oriented counselling was found to be effective in improving partner referral outcomes. CONCLUSIONS: STD clinics can improve PN with client-oriented counselling, which should help clients to overcome perceived barriers. The authors speculate that well-designed PN interventions to evaluate the impact on STI prevalence and incidence along with cost-effectiveness components will motivate policy makers in developing countries to allocate more resources towards STI management.

Determinants of low birth weight in urban Pakistan.

OBJECTIVE: To identify determinants of low birth weight (LBW) in Karachi, Pakistan, including environmental exposures and nutritional status of the mother during pregnancy. DESIGN: Cross-sectional study.ParticipantsFive hundred and forty mother-infant pairs. We interviewed mothers about obstetric history, diet and exposure to Pb. We measured birth weight and blood lead level (BLL). We performed multiple log binomial regression analysis to identify factors related to LBW. RESULTS: Of 540 infants, 100 (18.5 %) weighed 208.7 mg/d), infants of mothers with MUAC less than or equal to the median and dietary vitamin C intake >208.7 mg/d (adjPR = 10.80; 95 % CI 1.46, 79.76), mothers with MUAC above the median and vitamin C intake

Tuberculosis co-morbidity and perceptions about health care among HIV-infected plasma donors in rural China.

Limited community-based data exist about pulmonary tuberculosis (TB) comorbidity among HIV-infected individuals in China and no data exists about the TB burden in key high risk groups. We recruited 195 known HIV-infected plasma donors in one central China county and identified 9 (4.6%) active TB cases based on clinical assessment, including chest radiography. The low percentage of TB may be explained by improved immunity due to antiretroviral therapy.

Maternal nutritional status during pregnancy and surma use determine cord lead levels in Karachi, Pakistan.

OBJECTIVES: To estimate the umbilical cord blood lead levels (BLLs) of Pakistani neonates and to identify determinants for umbilical BLLs. METHODS: We conducted a cross-sectional study of mothers and infants at one of the two obstetric units of two tertiary care hospitals in Karachi during January-August 2005. Information from 540 mothers selected randomly from those registered for delivery was obtained about their pregnancy, diet, and current and past lead exposures. We collected umbilical cord blood for lead levels analyzed using graphite furnace atomic absorption spectrophotometry. We computed geometric and arithmetic means. We performed multiple linear regression analysis to identify factors associated with log-transformed umbilical cord BLLs. We also performed logistic regression analysis to identify determinants of high lead cord BLLs (10 microg/dl). RESULTS: The geometric mean cord BLL of the neonates was 9.6 microg/dl; arithmetic mean (S.D.) was 10.8 microg/dl (5.7) with a median of 9.7 microg/dl and a range of 1.8-48.9 microg/dl. Women who reported intake of less than 58.5mg of elemental iron supplement per day during pregnancy had cord BLL of 10.0 microg/dl; in comparison those women who had higher iron intake had lower cord BLL (8.4 microg/dl). Those who used surma (an eye cosmetic) daily had higher cord BLL (11.5 microg/dl) as compared to those who used it less frequently (9.4 microg/dl). In multivariable linear regression model, higher iron intake, owning a car, and being in 2nd quartile of mid-arm circumference were associated with low lead levels while father's occupation in lead-based industry was associated with significantly higher umbilical cord BLLs. There was interaction of daily surma use and ethnicity. Geometric mean BLLs were varied among surma users by ethnicity. CONCLUSIONS: Umbilical cord BLLs are high in Karachi, Pakistan, in comparison to those in developed countries such as United States. Measures are needed to reduce fetal lead exposure to prevent adverse affect on neurocognitive development. Association of low iron (below RDA of 60 mg per day) with high umbilical cord has implications for strengthening iron supplement intake during pregnancy. Umbilical cord BLLs differed among surma users by ethnicity.

Expansion of HIV/AIDS in China: lessons from Yunnan Province.

In this article we systematically and critically review the Chinese and English language literature on human immunodeficiency virus (HIV)-related studies in Yunnan Province, Southwestern China. Yunnan Province had the first Chinese HIV outbreak and is still the worst affected area in the nation. Since 1989, HIV infection has extended from injecting drug users into the general population through sexual transmission. Since the economic reform of the 1980s, changed social norms and increased migration have spawned increases in HIV-related risk behaviors such as drug use and commercial sex work. A smaller size of "bridge" populations and lower sexual contact rates between persons in "bridge" and general populations may explain the slower expansion of the HIV epidemic in Yunnan compared to nearby Southeast Asian nations. In 2004, women in antenatal care had a 0.38% HIV prevalence province wide, although >1% infection rates are seen in those counties with high injection drug rates. Patterns of drug trafficking have spread the unusual recombinant HIV subtypes first seen in Yunnan to far-flung regions of China. Increased efforts of Yunnan's HIV control program are correlated with an improved general HIV awareness, but risk behaviors continue at worrisome rates. Future efforts should focus on changing risk behaviors, including harm reduction and condom promotion, especially among the "bridge" groups. The resurgence of commercial sex work in Yunnan, and the high frequency of workers migrating into provinces far from home and family are all sociocultural factors of considerable importance for future HIV and sexually transmitted disease control in China.

SGA subtypes and mortality risk among singleton births.

OBJECTIVES: To determine whether early mortality (first year of life) risks among small for gestational age (SGA) neonates were similar regardless of SGA subtype based on three chronological classifications (term, preterm and post-term). STUDY DESIGN: Retrospective cohort study on all singleton live births in the United States from 1995 to 1999 inclusive. Adjusted risk estimates were computed from logistic regression models using non-SGA infants as the referent. RESULTS: When SGA infants were compared as a homogeneous entity to non-SGA infants, the risks for infant, neonatal and post-neonatal mortality were significantly greater in SGA infants [AOR (adjusted odds ratio)=3.0, 95% CI (confidence interval)=2.9-3.0 for infant mortality; AOR=3.2, 95% CI=3.1-3.2 for neonatal mortality; and AOR=2.6, 95% CI=2.6-2.7 for post-neonatal mortality]. However, heterogeneity existed in terms of mortality risk thresholds across SGA babies. The most remarkable risk magnitude was observed among preterm SGA infants [infant mortality AOR=13.8, 95% CI=13.6-14.1; neonatal death AOR=17.4, 95% CI=17.0-17.7; and post-neonatal death AOR=7.4, 95% CI=7.1-7.6]. The adjusted odds ratio for term and post-term SGA infants were comparable regardless of the period during infancy, and were much less than those observed for preterm SGA infants. CONCLUSIONS: SGA is a heterogeneous disease in terms of prognosis for survival. Preterm SGA infants bear an extremely high risk for mortality during infancy, and counseling of affected parents should reflect this risk divergence.

Is small for gestational age a marker of future fetal survival in utero?

OBJECTIVE: We sought to assess whether small for gestational age is a risk factor for stillbirth of a subsequent sibling. METHODS: The Missouri maternally linked cohort data set, containing data on births from 1978 through 1997, was used. We identified the study group (women who delivered a SGA infant in the first pregnancy) and a comparison group (women who delivered a non-SGA infant in their first pregnancy) and compared the outcome (stillbirth) in the second pregnancy between both groups. RESULTS: We analyzed information on the first and second pregnancies of 402,015 women (43,549 [10.8%] in the study arm and 358,466 [89.2%] in the comparison arm). Of the 1,883 cases of stillbirth in the second pregnancy, 314 cases occurred in mothers with a history of SGA (stillbirth rate 7.2/1,000) and 1,569 in the comparison group (stillbirth rate 4.4/1,000), P < .001. The adjusted risk of stillbirth was 60% higher in women with a prior SGA (odds ratio [OR] 1.6, 95% confidence interval [CI] 1.4-1.8). The risk for stillbirth in the second pregnancy increased with decreasing gestational age at birth of the SGA infant in the first pregnancy (term: OR 1.4, 95% CI 1.2-1.6; preterm: OR 2.8, 95% CI 2.0-3.8; and very preterm: OR 4.2, 95% CI 2.4-7.3), P for trend < .001. CONCLUSION: Small for gestational age is a marker for subsequent stillbirth, and the risk rises with decreasing gestational age of the SGA birth. This information is potentially useful for counseling parents of SGA infants. LEVEL OF EVIDENCE: II-2.

Risk of stillbirth following a cesarean delivery: black-white disparity.

OBJECTIVE: We examine the association between prior cesarean delivery and risk of stillbirth in a subsequent pregnancy. METHODS: The Missouri maternally linked cohort data set containing births from 1978 through 1997 was used. We identified a cohort of women who delivered live births by cesarean delivery and a comparison cohort of women who delivered live births vaginally in their first pregnancies. We then compared the risks of stillbirth in the second pregnancy between the 2 groups. RESULTS: We analyzed 396,441 women with information on first and second pregnancies, comprising 71,950 (18.1%) in the cesarean arm, and 324,491 (81.9%) in the vaginal birth arm. Rates of stillbirth among women with and those without history of cesarean delivery were 4.4 and 4.1 per 1,000 births, respectively (P = .2). The adjusted estimates also showed no difference in risk for stillbirth between the 2 groups (odds ratio [OR] 1.1, 95% confidence interval [CI] 1.0-1.3). Among whites, the stillbirth rates in women with and those without history of cesarean delivery were 3.7 and 3.6 per 1,000 births, respectively (OR 1.0, 95% CI 0.9-1.2). Among blacks, both the absolute and the adjusted relative risks for stillbirth were elevated in mothers with history of cesarean delivery (stillbirth rate 9.3 versus 6.8 per 1,000 births; OR 1.4, 95% CI 1.1-1.7). CONCLUSION: Overall, our analysis did not detect an association between cesarean history and subsequent stillbirth. However, cesarean delivery may increase the risk for subsequent stillbirth among black mothers, a group with the highest cesarean delivery rate in the country. LEVEL OF EVIDENCE: III.

From conflict to collaboration, local political climate accelerates ITREOH's regionalization in South Asia.

As Pakistan becomes industrialized, the development of human resources is essential to addressing emerging health problems. The Fogarty International Center (FIC)-funded University of Alabama at Birmingham (UAB)-Aga Khan University (AKU) ITREOH initiative has been instrumental in filling the gaps in environmental and occupational health (EOH) training and research. Because of travel impediments to Pakistan, a regional short-term training program was implemented in Nepal and Sri Lanka. Workshop participants were from Pakistan, Nepal, Sri Lanka, India, and Bangladesh. The training programs enhanced north-to-south and south-to-south collaboration in research and training in South Asia. A major impact is the development of a certificate program in EOH at AKU. Research initiatives of regional and/or global concern are also under way in the other participating countries. The combination of face-to-face training with Web-based interaction for follow-up was optimal for short-term training.

Stillbirth and infant mortality among Hispanic singletons, twins, and triplets in the United States.

OBJECTIVE: We estimate the impact of increasing fetal number on fetal and infant mortality among Hispanic mothers. METHODS: Retrospective cohort study involving singletons, twins, and triplets delivered in the United States from 1995 through 2000, except for the analysis on infant mortality in singletons (1995 through 1999). Main outcome measures were stillbirth (> or = 20 weeks) and infant mortality (< 365 days). RESULTS: A total of 37,489,600 individual births were reviewed, consisting of 36,840,704 singletons, 613,930 twins, and 34,966 triplets. Hispanics accounted for 6,848,027 (18.6%) singletons, 85,887 (14.0%) individual twins, and 2,725 (7.8%) individual triplets. Among singletons, stillbirth (odds ratio [OR] 0.91, 95% confidence interval [CI] 0.90-0.92) and infant mortality (OR 0.85, 95% CI 0.84-0.86) were both lower in Hispanics than in whites. Among twins, Hispanics had a lower risk for infant mortality (OR 0.93, 95% CI 0.88-0.97) but a comparable risk for stillbirth (OR 1.06, 95% CI 0.98-1.13). Although the risk for infant mortality in Hispanic triplets was comparable to that of whites (OR 1.20, 95% CI 0.94-1.54), Hispanic triplets had a 50% higher likelihood of dying in utero (OR 1.50, 95% CI 1.06-2.14). CONCLUSION: Although Hispanic infants generally show better or comparable survival indices compared with whites, the risk for fetal and infant death in Hispanics increases in fetal number in a dose-dependent fashion, thereby obliterating the Hispanic advantage. The elevated risk for stillbirth among Hispanic triplets is particularly noteworthy and underscores the need for caution in making generalizations of favorable birth outcomes in Hispanics.

Sexually transmitted infections among pregnant women attending antenatal clinics in Mongolia: potential impact on the Mongolian HIV epidemic.

We conducted Mongolia's first nation-wide cross-sectional survey of sexually transmitted infections (STIs) among pregnant women attending prenatal care. Among our 2000 participants, 386 (19.3%) were infected with Chlamydia trachomatis, 133 (6.7%) with Trichomonas vaginalis, 121 (6.1%) with Neisseria gonorrhoeae, and 128 (6.4%) were seropositive for Treponemal antibodies. None of our participants were seropositive for HIV infection. Additionally, 605 (30.3%) of the women had at least one STI, 133 (6.7%) had a double infection, and 15 (0.8%) had a triple infection. Our results suggest that STIs are a serious problem in Mongolia. Pregnant women represent a lower-risk general population; these high STI rates suggest that at this nascent stage, the identification, treatment, and prevention of STIs as risk factors for HIV transmission are crucial in the prevention of the emerging Mongolian HIV epidemic.
