Is sense of belonging at school associated with cannabis use among secondary school students in Barbados?

The objective of this study was to assess whether students' sense of belonging at school was associated with cannabis use among secondary school students in Barbados. This was a cross-sectional study involving a nationally representative weighted sample of 8,538 students drawn from 2nd to 6th forms across public and private secondary schools in Barbados in 2013. Descriptive and inferential statistics was performed using SPSS. Students who had a sense of belonging at school, were attending public schools and were in the 2nd form, had higher odds of reporting past-year and past-month cannabis use. We conclude that there was a significant positive association between students' sense of belonging at school and cannabis use.

ASSOCIATION BETWEEN SINGLE-PARENT FAMILY STRUCTURE AND AGE OF SEXUAL DEBUT AMONG YOUNG PERSONS IN JAMAICA.

There is a high and increasing proportion of single-parent families in Jamaica. This has raised concerns about the potential impact of single-parent families on the social, cognitive and behavioural development of children, including their sexual relationships. The aim of this study was to investigate the association between being raised in a single-parent family and age of sexual debut among young people in Jamaica. The study was cross-sectional in design, and based on a multi-stage sampling procedure. The study was conducted in July/September 2016. The study sample comprised 233 respondents (110 males and 123 females) aged from 18 to 35 years (mean 26.37 years; SD 5.46). Respondents completed a self-administered questionnaire with questions on socio-demographic characteristics, family structure, sexual debut and current sexual behaviour. Ninety-seven (41.7%) respondents grew up in single-parent families. A total of 201 (86.3%) had had sex (102 males and 99 females). Their mean age of sexual debut was 15.51 years (SD 3.41). Sixty-five (32.3%) had early sexual debut (<16 years). Respondents from single-parent families were more likely to have had early sexual debut (56.9%; n=37) compared with those from two-parent families (43.1%, n=28; p=0.004). Only 44.6% (n=29) of those who experienced early sexual debut used a condom during their first sexual encounter compared with 73% (n=100) of those who had a later sexual debut (≥16 years; p=<0.001). A single-father family structure was a significant predictor of early sexual debut (AOR 5.5; 95%CI: 1.1-25.8). The study found a significant association between single-parent family structure and age of sexual debut.

Alcohol Consumption and Sexual Risk Behaviour among Jamaican Adolescents

Alcohol consumption has significant health, social and economic implications. Alcohol is the most prevalent psychoactive substance used by Jamaican adolescents. The aim of this study was to determine whether alcohol is associated with sexual risk behaviour among Jamaican adolescents. Methods: The data from National Secondary School Survey (NSS) conducted in 2013 was analysed. Descriptive statistics consisting of frequencies, percentages and Pearson's Chi square was done. Multivariate analysis was done using binary logistic regression. Result: The mean age of alcohol initiation among the participants was 12.3years [SD: 2.74]. There were significant associations between gender (X2= 14.56; p= 0.000), relationship with father/guardian (X2: 10.71; P= 0.03), relationship with mother (X2= 15.16; P= 0.004) and conversation with parents/ guardians about dangers of drug abuse (X2= 8.16; P=0.004). Adolescents who were males (AOR= 0.62, 95% CI= 0.43 - 0.88), in the 8th grade (AOR= 0.51, 95% CI= 0.26 - 0.98) or in the 10th grade (AOR: 0.52, 95% CI: 0.32 - 0.85) were less likely to engage in sexual risk behaviour. Lifetime alcohol consumption, past year alcohol consumption and past month alcohol consumption were not significantly associated with sexual risk behaviour (AOR= 0.35, 95% CI= 0.04 - 3.46; AOR= 1.75, 95% CI= 0.59 - 5.09, AOR= 0.78 95% CI= 0.56 - 1.11 respectively). Conclusion: Lifetime, past one year and past one month alcohol consumption among the students were not risk factors for sexual risk behavior (non-condom use) among Jamaican adolescents.

A School-Based Study of the Influence of Students' Relationship with Teachers on Their Cigarette Smoking Behaviour in Jamaican

Background: Cigarette is one of the most widely used addictive substances and a leading cause of death. Prevalence of cigarette smoking has been reported to be high in the Caribbean, including Jamaica. The aim of this study was to determine whether students' relationship with teachers influences their cigarette smoking behaviour in Jamaica. Methods: This was a statistical analysis of data based on a nationally representative sample of 3,365 secondary school students drawn from 8th to 12th grade across 38 secondary schools in Jamaica in 2013. Descriptive and inferential statistics were performed using SPSS. Results: There were significant differences in the past year and past month cigarette smoking respectively among students who had very good, good, average, bad and very bad relationship with their teachers (X2 = 11.67, p = 0.02; X2 = 9.61, p = 0.04) respectively. Students with very good relationship with teachers, were significantly less likely to report smoking cigarette in the past month (AOR= 0.09, 95% CI= 0.01- 0.88). Students who were 2 - 10 years, had very good relationship with teacher and father, and whose parents knew friends very well, were 0.96, 0.69, 0.70 and 0.94 times as likely to report smoking cigarette in the past year. However, these associations were not significant after controlling for other factors. Conclusion: Students' relationship with their teachers has a strong influence on cigarette smoking. Students with very good relationship with teachers were significantly less likely to report smoking cigarette in the past month.

Does Risk Perception Affect Alcohol Consumption among Secondary School Students in Jamaica?

Background: Alcohol consumption among young people is a major public health problem world-wide and in Jamaica. A number of factors have been reported to affect alcohol use among high school students. The aim of this study was to investigate the influence of perception of the harmfulness of alcohol on alcohol use among secondary school students in Jamaica. Methods: Data collected from a nationally representative sample of 3,365 students were analyzed. Descriptive and inferential statistics were performed using SPSS. Results: Students' perception of risk of drinking alcohol frequently and getting drunk respectively had positive and significant associations with past month alcohol use (AOR= 1.44, 95% CI= 1.09- 1.88 and AOR= 1.38, 95% CI= 1.02- 1.86, respectively) compared to students who felt that drinking alcohol frequently and getting drunk were very harmful. Males, 12 years or younger were significantly less likely to use alcohol in the past month (AOR= 0.77, 95% CI=0.60- 0.97; AOR= 0.68, 95% CI= 0.53-0.97 respectively). Students with good relationship with their mothers were less likely to use alcohol in the past year and past month (AOR= 0.55, 95% CI= 0.35-0.87; AOR= 0.50, 95% CI= 0.32- 0.78). Conclusion: Risk perception of the harmfulness of alcohol significantly affects alcohol use among secondary school students in Jamaica. Males, 12 years or younger, who had good relationship with mothers, were significantly less likely to use alcohol in past month

Single Parent Family Structure as a Predictor of Alcohol Use among Secondary School Students: Evidence from Jamaica

The aim of this study was to examine the potential relationship between Jamaican secondary students' alcohol drinking habits and their family structure. Methods: Data collected from a nationally representative survey of 3,365 students were analysed. Descriptive and inferential statistics were performed. Results: Out of the 3,365 students, 1,044 (31.0%) were from single-parent families. Single-parent families, married-parent families and common law-parent families were significantly associated with lifetime use of alcohol (AOR= 1.72, 95% CI= 1.06 - 2.79; AOR= 1.73, 95% CI= 1.07- 2.81, AOR= 1.94, 95%CI= 1.17- 3.21 respectively). However, family structure was not significantly associated with past year and past month alcohol use. Students whose parents "sometimes" knew their whereabouts were significantly less likely to use alcohol in their lifetime compared to students whose parents "Always" knew where the students were. Conclusion: Family structure is an independent predictor of alcohol use among high school students in Jamaica. Being from single-parent families, married-parent and common- law parent families were significantly associated with increased likelihood for lifetime alcohol use.

Are Adolescents likely to Start Smoking Early if Their Parents are Smokers? A Study of Jamaican High School Students

Background: The prevalence of cigarette smoking is high among adolescents in the Caribbean, including Jamaica. Age of initiation of cigarette smoking varies among adolescents. A number of factors has been reported to influence early age of initiation of cigarette smoking. The aim of this study was to determine if parental smoking status was associated with early age of onset of cigarette smoking among Jamaican adolescents. Methods: Data from the Jamaican National School Survey (NSS) conducted in 2013 were analysed. The nationally representative sample comprised of 3,365 students enrolled in 8th grade to 12th grade in 38 public and private secondary schools. Descriptive and inferential statistics were computed using SPSS. Results: The mean age of initiation of cigarette smoking among the subjects was 12.4years [SD: 2.69]. There was no significant association between parental cigarette smoking status and the age of initiation of cigarette smoking among the adolescents (female X2 = 0.753, P = 0.861; male X2 = 6.953, P = 0.073). Logistic regression analysis showed that parental smoking status was not a predictor of early age of initiation of cigarette smoking among the adolescents (father/ guardian AOR= 0.81, 95% CI= 0.56- 1.11; mother/guardian AOR= 0.96, 95% CI= 0.44 ­ 2.10; both parent AOR= 0.49, 95%CI= 0.22- 1.07). However, having a parent with secondary education was a risk factor for early initiation of smoking (AOR= 1.71, 95%CI= 1.13-2.57), while being in 8th grade was a protective factor against early age of initiation of cigarette smoking (AOR= 0.43, 95% CI= 0.23 - 0.80). Conclusion: Parental smoking cigarette smoking status was not a predictor of early age of cigarette smoking initiation among Jamaican adolescents.

A Population-based Analysis of the Influence of Religious Affiliation on Alcohol Consumption among Jamaicans

Background: Religion sometimes shapes behaviours and experiences of its members including alcohol consumption. The aim of this study was to examine the possible influence of religious affiliation on alcohol consumption in Jamaica since they are predominantly Christians. Methods: Using a cross-sectional study design, we analysed data from National Household Survey 2,016 of 4,623 participants. Descriptive and inferential statistics were performed using SPSS. Results: Out of the 4,623 participants, majority 3,244 (70.2%) were above the age of 26 years and of Christian religion 3,737 (80.8%). Christian religious affiliation was significantly associated with past year and past month use of alcohol (AOR= 1.44, 95% CI=1.14-1.82 and AOR =1.34, 95% CI=1.03- 1.74 respectively). Being a male (AOR= 2.95, 95% CI=2.51- 3.47), and employed (AOR= 2.11, 95% CI= 1.49- 2.98) were significant risk factors for lifetime alcohol consumption. Age 12 ­ 17 years (AOR= 0.30, 95% CI=0.21- 0.43) and attaining primary education level (AOR=0.60, 95% CI=0.45-0.80) were protective factors against lifetime alcohol consumption. Conclusion: Being of Christian religion was significantly, positively associated with past year and past month alcohol consumption. Male gender and being employed were also risk factors for lifetime alcohol consumption.

Risk Factors Associated with Frequent Alcohol Binge Drinking among Jamaicans: Does Gender Matter?

Objective: Alcohol is one of the most commonly consumed substances in Jamaica, despite the many health problems associated with excessive alcohol use. The aim of this study was to identify potential risk factors for alcohol binge drinking among Jamaicans, and determine if there were significant gender differences in the associations between identified risk factors and frequent binge drinking. Methods: Data collected from the 2016 National Household Survey Jamaica were analysed. Descriptive and inferential statistics were computed using SPSS. Binary logistic regression analysis was used to determine factors associated with frequent binge drinking. Results: The total number of respondents was 4623. Females were 2,535 (54.8%) compared to males 2088 (45.2%). In bivariate analysis, there was a significant association between age and frequent binge drinking among males (X2 = 11.11, p =0.004), but not among females (X2 = 2.03, p = 0.36). Similarly, there was a significant association between employment and frequent binge drinking for males but not for females (X2= 12.85, p= 0.002; X2= 2.49, p= 0.29 respectively). In multivariate analysis, age 12- 17 years was significantly, inversely associated with frequent binge drinking in the crude logit model but not in the adjusted logit model (crude odds ratio [COR] 0.21, 95%CI= 0.6- 0.66; adjusted odds ratio [AOR] = 0.51, 95%CI= 0.12- 2.13 respectively). Employment was significantly, positively associated with frequent binge drinking in the adjusted logit model (employed: AOR= 3.63, 95% CI= 1.05- 12.59) among males. Among females, age showed no significant association with frequent binge drinking. Only having primary/ lower education was significantly, positively associated with frequent binge drinking among females (AOR= 5.17, 95%CI= 1.36- 19.65). Conclusion: Risk factors for frequent binge drinking differed by gender; being employed was a risk factor for males while having primary (or lower) education was a risk factor for females.

Alcohol Drinking among Primary School Children in Trinidad and Tobago: Prevalence and Associated Risk Factors

Background: Underage alcohol use is a pervasive problem with serious health, social and safety consequences. This study was undertaken to assess alcohol use by primary school children in Trinidad and Tobago, and to identify associated risk factors. Methods: We analysed data collected from 40 primary schools in Trinidad and Tobago by the National Alcohol and Drug Abuse Prevention Programme (NADAPP). The sample comprised of children aged 8 -15 years old, in standards 3, 4 and 5. Result: Out of the 2052 children, 648 (31.6%) have consumed alcohol in their lifetime, and same proportion reported ever being drunk (31.6%). Male gender was significantly associated with lifetime alcohol use (AOR =1.60, 95% CI= 1.25 - 2.05). Children not living with their father (AOR= 2.45, 95% CI=1.86- 3.24) and those whose fathers have either primary or secondary education (AOR = 1.88, 95%CI=1.07 - 3.31; AOR= 1.58, 95%CI=1.12 - 2.23 respectively) were at higher risk for lifetime alcohol consumption. However, age group 8 ­ 11 years was significantly inversely associated with lifetime alcohol consumption (AOR= 0.67, 95% CI=0.48 - 0.94). Conclusion: Being a male student, not living with father, and father attaining either primary or secondary education level were significantly associated with increased likelihood for lifetime alcohol use. However, children between 8 ­ 11 years were less likely to consume alcohol.

Investigating the Role of Alcohol in Behavioural Problems at School among Secondary School Students in Barbados

Background: The prevalence of alcohol use is quite high in the Caribbean region, and specifically, in Barbados. Alcohol use has been documented to negatively affect the way students behave within and outside school. This study set out to examine the role alcohol plays in students' behavioural problems at school. Methods: An analysis of crosssectional data collected during the National Secondary Schools Survey was done. Mean (and standard deviation), frequencies and percentages were computed, and differences in proportions among the groups were assessed using Pearson's Chi Square. Multivariate analysis using binary logistic regression was done to determine the association between explanatory variables and outcome variables. Results: In bivariate analysis, behavioural problems at school were significantly associated with age (p= 0.001), grade (p= 0.000), sense of belonging at school (p= 0.000), relationship with teachers (p= 0.000), and past month alcohol use (p= 0.007). In multivariate analysis, students' having frequent behavioural problems at school was significantly associated with neither past year nor past month alcohol use (AOR= 1.13, 95% CI= 0.91- 1.40, AOR= 1.02, 95% CI= 0.83- 1.24 respectively). Significant inverse associations were found between students' behavioural problems and age (11- 14 years: AOR= 0.53, 95% CI= 0.33- 0.84; AOR= 0.51, 95% CI= 0.32- 0.82 for models 1 and 2 respectively), and relationship with teachers (very good: AOR= 0.10, 95% CI= 0.07- 0.16; AOR= 0.13, 95% CI= 0.09- 0.20 for models 1 and 2 respectively). Conclusion: Neither past year nor past month alcohol consumption by students was associated with frequent behavioural problems at school. Students who were younger than 17 years, and who had a relationship with their teachers that was not very bad were significantly less likely to engage in frequent behavioural problems.

Parental Alcohol Drinking Habit as a Predictor of Alcohol Use among Secondary School Students in Barbados

Background: In Barbados and the wider Caribbean region, alcohol is widely consumed by adolescents and young people, including those in secondary schools. The high prevalence of alcohol use, and its potential adverse effects are a source of concern to policy makers and the general population, which calls for better understanding of the drivers of this problem. This study thus aimed at investigating whether parental alcohol drinking habit is a predictor of alcohol use among secondary school students in the country. Methods: The predictor variables and response variables in the study were categorical, and so descriptive, univariate analysis consisted of computation of frequencies and percentages. Bivariate analysis using Pearson's Chi Square was done to test for significant differences in the response variables among groups. Logistic regression modeling was used in multivariate analysis to determine the predictor variables that were significantly associated with the response variables. Results: Significant associations were seen between students' age, (P= 0.00), grade (P=0.00), fathers' drinking habit (P=0.00), mothers' drinking habit (P=0.00), and both past year and past month alcohol use, in bivariate analysis. Logit model shows that students whose fathers drink only on weekends, sometimes during the week, or every day, respectively, had significantly increased risk of alcohol use in the past month (AOR= 2.62, 95%CI= 1.81- 3.77; AOR= 1.85, 95%CI= 1.19- 2.85; AOR= 2.18, 95%CI= 1.49- 3.18). Students whose mothers drink only on special occasion had significantly higher risk of alcohol use in the past year and past month (AOR= 1.99, 95%CI= 1.06- 3.74; AOR= 2.30, 95%CI= 1.36- 3.89 respectively). Conclusion: Having fathers who drink only on weekend, sometimes during the week and every day were significantly positively associated with alcohol use in the past month. Having mothers who drink only on special occasion was a risk factor for past year and past month alcohol use. However, having mothers who drin

An evaluation of innovative community-based approaches and systematic tuberculosis screening to improve tuberculosis case detection in Ebonyi State, Nigeria.

BACKGROUND: National tuberculosis (TB) programmes globally rely heavily on passive case finding for detecting TB in the community as advocated by the World Health Organization (WHO). TB case detection is low in Nigeria despite improvement in TB services and coverage. METHODS: A retrospective evaluation of an active case-finding intervention utilizing community-based approaches and targeted systematic TB screening in Ebonyi State, Nigeria was done. The analysis was performed using Epi Info. RESULTS: Using community-based and health-facility-based systematic screening strategies, 218,751 persons were screened, with 19.7% of them being presumptive TB cases. Among these, 23,729 (55.1%) submitted sputum samples for microscopy, and 764 (3.2%) had smear-positive TB. In addition, 683 individuals were diagnosed with other forms of TB using X-ray and clinical evaluation giving a total of 1447 all forms of TB cases. The overall number needed to screen (NNS) to find one person with all forms of TB through the project was 151. The NNS was 53 for general outpatients, 88 through contact tracing, and 110 among HIV-infected persons. CONCLUSIONS: Active case-finding strategies achieved good yields though early loss to follow-up was high. Active case finding is recommended for integration into national TB control policy and practice.

Screening for diabetes mellitus among tuberculosis patients in Southern Nigeria: a multi-centre implementation study under programme settings.

Implementation studies are recommended to assess the feasibility and effectiveness of programmes. In Nigeria, little is known about the burden of diabetes mellitus (DM) among tuberculosis (TB) patients. The objective of this study was to determine screening efficacy, prevalence of DM and determinants of DM among TB patients. We report on a multi-centre implementation study carried-out in 13 health facilities in six States of Southern Nigeria. All newly diagnosed TB patients registered from March to October 2015 were screened for DM using current World Health Organisation guidelines. Overall, 2094 TB patients were evaluated, 196 (9.4%) were found to have DM. The prevalence of newly diagnosed DM was 5.5% (115/2094). DM prevalence varied according to age group; occurring in 2.2% of patients aged ≤ 25 years and 16.9% in patients aged (56-65) years. The additional yield of DM was 59% while the number needed to screen to detect a new case of DM was 18. Factors associated with DM were; age >40 years (aOR2.8, CI 2.1-3.9), rural residence (aOR2.3, 1.6-3.2), private health facility care (aOR2.0, 1.4-2.7), and having an occupation that engages in vigorous activity (aOR0.6, 0.4-0.9). The burden of DM among TB patients is high. Prioritization of DM screening for TB patients is indicated.

'Sustaining the DOTS': stakeholders' experience of a social protection intervention for TB in Nigeria.

Background: Social protection for TB patients can lower patient costs and improve adherence. The aim of this study was to explore patients' and health workers' experiences of a social protection intervention for TB in order to inform a more patient-centred approach for the Nigeria National TB Programme strategy. Methods: This was a qualitative study consisting of 103 in-depth interviews and two focus group discussions with patients who received the intervention, and 10 key informant interviews with health workers. A thematic content analysis of the interviews was performed. Results: Of those who completed the interviews, 53 (51.5%) were male, and 69 (67.0%) were below 40 years. Most of the participants received care and support from their families but delayed access to TB services due to lack of funds for transportation, nutritional supplementation and non-TB drugs. The intervention had a high level of acceptability and uptake; particularly clear benefits emerged for most patients who used the social protection funds to purchase food and supplements, other drugs, transportation and additional personal necessities. Some patients assert that the financial incentive package increased their awareness of timing of their follow-up visits. In addition, health workers observed increased enthusiasm to treatment and improvement in adherence among participants. Conclusions: Patients and health workers reported positive experiences with the financial incentives provided for TB treatment.

Financial burden of health care for Buruli ulcer patients in Nigeria: the patients' perspective.

BACKGROUND: The economic burden of Buruli ulcer for patients has not been well-documented. This study assessed the costs of Buruli ulcer care to patients from the onset of illness to diagnosis and to the end of treatment. METHODS: This was a cross-sectional cost of illness study conducted among patients with Buruli ulcer in four States in Nigeria between July and September 2015. A structured questionnaire was used to collect data on the patients' characteristics, household income and out-of-pocket costs of care. RESULTS: Of 92 patients surveyed, 54 (59%) were older than 15years, 49 (53%) were males, and 86 (93%) resided in a rural area. The median (IQR) direct medical and non-medical cost per patient was US$124 (50-282) and US$3 (3-6); corresponding to 149% and 4% of the patients' median monthly household income, respectively. The overall direct costs per patient was US$135 (58-327), which corresponded to 162% of median monthly household income, with pre-diagnosis costs accounting for 94.8% of the total costs. The direct costs of Buruli ulcer care were catastrophic for 50% of all patients/households - the rates of catastrophic costs for Buruli ulcer care was 66% and 19% for patients belonging to the lowest and highest income quartiles, respectively. CONCLUSIONS: Direct costs of Buruli ulcer diagnosis and treatment are catastrophic to a substantial proportion of patients and their families.

Diagnosis delay and duration of hospitalisation of patients with Buruli ulcer in Nigeria.

BACKGROUND: Delayed diagnosis of Buruli ulcer can worsen clinical presentation of the disease, prolong duration of management, and impose avoidable additional costs on patients and health providers. We investigated the profile, delays in diagnosis, duration of hospitalisation, and associated factors among patients with Buruli ulcer in Nigeria. METHODS: This was a prospective cohort study of patients with Buruli ulcer who were identified from a community-based survey. Data on the patients' clinical profile, delays in diagnosis and duration of hospitalisation were prospectively collected. RESULTS: Of 145 patients notified, 125 (86.2%) were confirmed by one or more laboratory tests (81.4% by PCR). The median age of the patients was 20 years, 88 (60.7%) were >15years old and 85 (58.6%) were females. In addition, 137 (94.5%) were new cases, 119 (82.1%) presented with ulcers and 110 (75.9%) had lower limb lesions. The mean time delay to diagnosis was 50.6 (±101.9) weeks. The mean duration of hospitalisation was 108 (±60) days. Determinants of time delay to diagnosis were higher disease category (p=0.001) and laboratory confirmation of disease (p=0.02). Determinants of longer hospitalisation were; multiple lesions (p=0.035), and having functional limitation at diagnosis and undertaking surgery (p=0.003). CONCLUSIONS: Patients with Buruli ulcer have very long time delays to diagnosis and long hospitalisation during treatment. This calls for early case-finding and improved access to Buruli ulcer services in Nigeria.

Assessment of current practices in management of childhood TB among frontline clinicians in Southern Nigeria.

BACKGROUND: Poor competence of clinicians may be a critical factor responsible for the under-diagnosis of childhood TB in high-burden settings. Our objective was to assess the current practices of management of childhood TB among clinicians in Nigeria. METHODS: A cross-sectional survey was conducted among clinicians recruited through a three-stage sampling technique from 76 health facilities in Southern Nigeria. A semi-structured questionnaire was administered to all participants. RESULTS: Of 106 clinicians who completed the survey, 73 (68.9%) were <40 years and 67 (63.2%) were males. Also, 14 (13.2%) were paediatricians, 22 (20.8%) were paediatric specialist trainees and 70 (66%) were medical officers in primary and secondary care health facilities. About 94% of the respondents perceived diagnosis of childhood TB a challenge in Nigeria. The overall mean (SD) knowledge score was 3.8±0.9 (maximum 5), and 68 (64.2%) had good knowledge of childhood TB. The mean (SD) appropriate practice score was 4.0±1.7 (maximum 10) and, only 8 (7.5%) of them were considered to have adopted appropriate practices regarding childhood TB care. CONCLUSIONS: There are gaps in practices adopted by frontline clinicians in the management of childhood TB in Nigeria. Focused training of health workers on childhood TB care is urgently recommended.

Buruli ulcer in Nigeria: results of a pilot case study in three rural districts.

BACKGROUND: Buruli ulcer (BU), also known as Mycobacterium ulcerans disease, is the third most common mycobacterial disease worldwide. Although BU disease has been diagnosed among Nigerians in neighbouring West African countries, data on the burden of the disease in Nigeria itself are scanty. This study aimed to assess the magnitude and epidemiology of BU in the South South region of Nigeria. METHODS: We conducted a cross-sectional survey in the Ogoja territory (comprising 31 communities). We undertook sensitisation programmes centred on BU in 10 of the communities. Participants were asked to identify community members with long-standing ulcers, who were then invited for evaluation. We also contacted traditional healers to refer their clients who had non-healing ulcers. All suspected cases had a full clinical evaluation and laboratory testing. Confirmed cases were given treatment in a referral hospital in the territory. RESULTS: We diagnosed 41 clinical BU cases; 36 (87.8 %) of which were confirmed by quantitative polymerase chain reaction (qPCR). These 36 PCR-confirmed cases were diagnosed in a total population of 192,169 inhabitants. Therefore, the estimated crude prevalence of BU was 18.7 per 100,000 population, varying from 6.0 to 41.4 per 100,000 in the districts surveyed. The majority (66.7 %) of the cases were females. About 92 % of the BU lesions were located on the patients' extremities. No differences were observed between the sexes in terms of the location of the lesions. The age of the patients ranged from four to 60 years, with a median age of 17 years. All 35 (100 %) patients who consented to treatment completed chemotherapy as prescribed. Of the treated cases, 29 (82.9 %) needed and received surgery. All cases healed, but 29 (82.9 %) had some limitations in movement. Healing with limitations in movement occurred in 18/19 (94.7 %) and 8/10 (80.0 %) of patients with lesions >15 cm (Category III) and 6-15 cm in diameter (Category II), respectively. The median duration of treatment was 130 (87-164) days for children and 98 (56-134) days for adults (p = 0.15). CONCLUSIONS: In Nigeria, BU is endemic but its severity is underestimated-at least in the study setting. There is a need to identify and map BU endemic regions in Nigeria. A comprehensive BU control programme is also urgently needed.

Does intensified case finding increase tuberculosis case notification among children in resource-poor settings? A report from Nigeria.

OBJECTIVE/BACKGROUND: Tuberculosis (TB) is a major cause of morbidity and mortality in developing countries. Passive case detection in national TB programmes is associated with low case notification, especially in children. This study was undertaken to improve detection of childhood TB in resource-poor settings through intensified case-finding strategies. METHODS: A community-based intervention was carried out in six states in Nigeria. The creation of TB awareness was undertaken, and work aids, guidelines, and diagnostic charts were produced, distributed, and used. Various cadres of health workers and ad hoc project staff were trained. Child contacts with TB patients were screened in their homes, and children presenting at various hospital units were screened for TB. Baseline and intervention data were collected for evaluation populations and control populations. RESULTS: Detection of childhood TB increased in the evaluation population during the intervention, with a mean quarterly increase of 4.0% [new smear positive (NSP), although the increasing trend was not statistically significant (χ(2)=1.8; p<.179)]. Additionally, there was a mean quarterly increase of 3% for all forms of TB, although the trend was not statistically significant (χ(2)=1.48; p<.224). Conversely, there was a decrease in case notification in the control population, with a mean decline of 3% (all forms). Compared to the baseline, there was an increase of 31% (all forms) and 22% (NSP) in the evaluation population. CONCLUSION: Intensified case finding combined with capacity building, provision of work aids/guidelines, and TB health education can improve childhood-TB notification.
