Sandflies in rural localities in northwest Paraná State, Brazil

This study reports the results from sandfly captures at six sites in a rural area of Japurá, Paraná State, Brazil, showing the vector's presence indoors, outdoors, and in residual forest. Sandfly captures were performed with Falc?o traps from 8:00 AM to 3:00 PM. At sites 195, 223, 236, and 527, three captures were performed at different times from December 2007 to January 2009. At sites 175 and 218, captures were performed from January to December 2008. 8,453 sandflies were captured, with an average of 155.40 specimens per hour. Nyssomyia neivai was the predominant species. Most sandflies were captured in domestic animal shelters (75.91 per hour) and in ciliary forest (38.45 per hour) during the hottest and rainiest months, in the outdoor environment with accumulation of organic matter and inadequate disposal of household wastewater. The study emphasizes the need for regular outdoor cleaning around households and building domestic animal shelters far from residences.     

Could we care for Amillia in rural Australia?

Extremely premature and very low birth weight infants have multiple, costly and complex health and developmental issues. After the neonatal period, the best chance for these children to avoid extreme disability and dependence, and thereby reach their potential, is with timely and intensive early intervention by appropriate allied health services, such as speech, occupational and physiotherapy. However, currently in rural Australia, such children are further disadvantaged by their relative lack of access to appropriate types and levels of services, compared with their urban counterparts.     

What constitutes an obesogenic environment in rural communities?

PURPOSE: To identify perceived indicators of the physical environment associated with obesity in rural communities. DESIGN: Cross-sectional telephone survey. SETTING: Thirteen communities in rural Missouri, Tennessee, and Arkansas, 2003. SUBJECTS: A total of 2510 adults completed the survey and 2210 respondents were included in the analysis (74% female, 93% white, and 27% obese). MEASURES: The 106-item survey measured perceptions of the neighborhood environment (recreational facilities, land use, transportation/safety, aesthetics, and food environment) and health-related behaviors. The primary outcome was obese (body mass index [BMI] > or = 30 kg/mn2) vs. normal weight (BMI = 18.5-24.9 kg/m2). ANALYSIS: Logistic regression was used to control for age, gender and education. RESULTS: Several indicators of the perceived neighborhood environment were associated with being obese (adjusted odds ratio [95% confidence interval]), including furthest distance to the nearest recreational facility (1.8 [1.3-2.4]), unpleasant community for physical activity (1.8 [1.3-2.6]), feeling unsafe from crime (2.1 [1.5-2.9]) or traffic (1.7 [1.2-2.3]), and few nonresidential destinations (1.4 [1.0-1.9]). Distance to recreational facilities and crime safety remained significant in the multivariate model, along with dietary-fat intake, sedentary behavior, and moderate/vigorous physical activity. CONCLUSION: This study adds to a growing evidence base of environmental correlates of obesity and makes a unique contribution regarding rural communities. If causality is established, environmental interventions that target obesogenic neighborhood features may reduce the prevalence of obesity on a population level.     

Malaria incidence in rural Benin: does economics matter in endemic area?

Malaria represents a major health problem with over 1 million annual deaths in Africa alone. There are a limited number of policies tackling the health problems of people at greater risk, namely the poor and rural communities. This is partly due to the lack of evidence available on the range of factors affecting their health status. Despite endemic malarial situations, there is still little understanding of the relative importance of economic factors that contribute to people acquiring malaria. This paper examines the socio-economic and economic factors that affect the incidence of malaria in rural community households in Benin, where malaria is endemic. A sample of 1585 households was determined to collect information on socio-economic characteristics and the presence of malaria symptoms. Probit estimation techniques were used to assess the impact of socio-demographic and socio-economic factors on the incidence of malaria, comparing households with and without malaria patients. Predisposing characteristics of the household head such as age, knowledge of malaria, education and the size of the household significantly affect the incidence of malaria as anticipated by economic theory. Enabling factors reflecting higher economic status, measured by monthly expenditure and a socio-economic index, have a statistically significant and positive impact on the incidence of malaria. This could reflect that better-off have improved case reporting and are likely to seek treatment. Variations in socio-economic and economic characteristics are significant in explaining the incidence of malaria, even in an endemic malarial setting.     

Starting rural,staying rural: How can we strengthen the pathway from rural upbringing to rural practice?

Objective: To determine if selecting rural background students into the Monash Bachelor of Medicine and Bachelor of Surgery (MBBS) program affects vocational training location and intended practice location after training. Design: Retrospective cohort mail survey. Setting: Australia. Participants: Rural‐background students at Monash 1992–1994 (n = 24/40) and 1995–1999 (n = 59/120) and urban background students (n = 36/93 and 104/300, respectively). Overall study population: 62% female, average age of 28 years; 79% Australian‐born; and 60% married/partnered. Interventions: Rural or urban background, rural undergraduate exposure. Main outcome measures: Intent towards rural medical practice, vocational training location and subsequent practice location. Results: There was a positive and significant (P ≤ 0.05) association between rural background and rural practice intent when respondents began (10‐times higher than urban graduates) and completed (three times higher) their MBBS course. Rural practice intent increased fourfold in urban background graduates. There was a positive and significant association between rural background and preferred place of practice in 5–10 years in a Rural, Remote and Metropolitan Area (RRMA) 3–7 community (three times higher). There was a positive, but non‐significant association between rural background and RRMA 3–7 community as their current location and first place of practice once vocationally qualified. Conclusions: Interest in rural practice is not fully reflected in location during or after vocational training. The beneficial effects of rural undergraduate exposure might be lost if internship and vocational training programs provide insufficient rural clinical experiences and curriculum content. Continuation of the rural pathway might be needed to maintain rural practice intent.     

Obesity: does it occur in African children in a rural community in South Africa?

BACKGROUND: Total body fatness and a centripetal fat patterning are recognized as risk indicators of cardiovascular disease in adulthood. In this study, the development of these risk factors in rural South African children during the preschool years and first years of formal schooling is explored. METHOD: The initial cross-sectional data from the Ellisras Longitudinal Investigations in Rural Community Children Project, ongoing since 1996, were used, involving 684 boys and 652 girls, aged 3-10 years, in the Ellisras rural community. Overweight was measured using the body mass index (BMI) (kg/m2). Overfatness was based on the sum of the triceps and subscapular skinfold thicknesses. A centripetal fat patterning was measured by the sum of trunk skinfolds relative to limb skinfolds and the ratio of the subscapular to triceps skinfold. Further, the ratio of the subscapular to supraspinale skinfold was used as an indicator of lower body fat patterning. The 85th percentiles of the NHANES III were used as cutoff values for overweight, overfatness and a centripetal fat patterning. RESULTS: At ages 7 and 8 years, mean BMI was statistically significantly higher in males compared to females (P < 0.05). The log transformed supraspinale skinfold thickness was larger in females compared to males at ages 4-7 years; the log transformed subscapular skinfold was larger in girls compared to boys aged 7-10 years. Less clear patterns were found for the extremity skinfolds and the skinfold ratios. Very few children (0-2.5% in males and 0-4.3% in females) had BMI values above the NHANES III 85th percentiles, indicating a very low prevalence of overweight children in the area. About 15% of the males showed overfatness at ages 3-4 years, while low prevalence was found at older ages. CONCLUSION: Few Ellisras rural children had above normal values for BMI, indicating a low prevalence of obesity in this population. In the 3- and 4-year-old group more subjects were found to have excessive fat, as indicated by the sum of the triceps and subscapular skinfold thicknesses.     

Do students from rural backgrounds engage in rural family practice more than their urban‐raised peers?

INTRODUCTION: In a previous prospective study, students from rural backgrounds were found to be significantly more likely to consider rural practice than their urban-raised peers. The purpose of this study was to determine whether the students with rural backgrounds who participated in the original investigation were more likely than their urban-raised peers to be currently engaged in rural family practice. METHOD: In Canada, family doctors have the greatest opportunity to practise in rural communities. Consequently, rural and urban background students from the original study who entered the discipline of family medicine as a career were identified for practice location follow-up. Participants were categorised as either rural (population less than 10 000) or urban practitioners according to the population of the community in which they practised. The proportion of rural and urban background students engaged in rural or urban practice was analysed using chi-square and relative risk probability. RESULTS: A total of 78 students from the original cohort were found to be practising family medicine; 22 of them had been rurally raised. Seven (32%) of the rural background students were practising in a rural community, compared to 7 (13%) of the 56 urban background students (RR = 2.55; P < 0.05). CONCLUSIONS: Rural background students who went on to complete family medicine residency training were approximately 2.5 times more likely to be engaged in rural practice than their urban-raised peers. Altering medical school admission policy to recruit more rural background applicants should be part of a multi-dimensional approach to increasing the number of rural practitioners.     

Does smoking affect schooling? Evidence from teenagers in rural China

Youth smoking can biologically reduce learning productivity. It can also reduce youths' expected returns to education and lower their motivation to go to school, where smoking is forbidden. Using rich household survey data from rural China, this study investigates the effect of youth smoking on educational outcomes. Youth smoking is clearly an endogenous variable; to obtain consistent estimates of its impact, we use counts of registered alcohol vendors and a food price index as instrumental variables. Since the variable that measures smoking behavior is censored for non-smoking adolescents, we implement a two-step estimation strategy to account for the censored nature of this endogenous regressor. The estimates indicate that smoking one cigarette per day during adolescence can lower students' scores on mathematics tests by about 0.08 standard deviations. However, we find no significant effect of youth smoking on either Chinese test scores or total years of schooling.     

Blood retinol and β-carotene levels in rural Guatemalan preschool children

Plasma retinol and -carotene levels were measured in 502 preschool Guatemalan children from five rural hamlets. Their ages ranged from 6 to 78 months (mean: 42.9±19.2 months); 45% males and 55% females. The mean retinol value in the whole group was 0.9±0.4 µmol/1 (range: 0.1 to 8.4 µmol/1). There was no significant difference between sexes in retinol mean values nor in the incidence of retinol values less than 0.7 µmol/1 (22% in males, 18% in females). When grouped by age and community, significant low retinol mean values were found in two hamlets in the youngest age group (12 to 23 months) as compared to the other age-groups (p<0.05). In the other two hamlets, there were no significant differences among retinol means by age-group. The highest prevalence of deficient retinol values by age-group was in the 12 to 23 months group (40%), and decreased as age increased. The mean value for -carotene in the whole group was 0.13±0.18 µmol/1 (range: 0.01 to 2.23 µmol/1). There were no significant differences in -carotene means between sexes in the whole group. Stratifying the -carotene data by age-groups and community, values were significantly higher in the 48–59 months and 72–83 months groups, as compared with the other age groups in two of the communities (p<0.05). Significant differences across communities for -carotene were found only in the 12 to 23 months group.     

Midwifery provision in two districts in Indonesia: how well are rural areas served?

Attention has focused recently on the importance of adequate and equitable provision of health personnel to raise levels of skilled attendance at delivery and thereby reduce maternal mortality. Indonesia has a village-based midwife programme that was intended to increase the rate of professional delivery care and redress the urban/rural imbalance in service provision by posting a trained midwife in every village in the country. We present findings on the distribution of midwifery provision in our study area: 10% of villages do not have a midwife but a nurse as a midwifery provider; there is a deficit in midwife density in remote villages compared with urban areas; those assigned to remote areas are less experienced; midwives manage few births and this may compromise their capacity to maintain professional skills; over 90% of non-hospital deliveries take place in the woman's (64%) or the midwife's (28%) home; three-quarters of midwives did not make regular use of the fee exemption scheme; midwives who live in their assigned village spend more days per month on clinical work there. We conclude that adequate provider density is an important factor in effective health care and that efforts should be made to redress the imbalance in provision, but that this can only contribute to reducing maternal mortality in the context of a supportive professional environment and timely access to emergency obstetric care.     

An offer you can't refuse? Provider-initiated HIV testing in antenatal clinics in rural Malawi

International organizations promote provider-initiated, 'routine' HIV testing of pregnant women seeking antenatal care as an effort to curb mother-to-child transmission. We offer an account of the perceptions of HIV testing at antenatal clinics in rural Malawi. Although it is both international and Government of Malawi policy that women must be explicitly informed of their right to refuse testing, analysis of in-depth interviews, focus group discussions and evidence from observational field journals show that rural Malawians do not perceive HIV testing as a choice, but rather as compulsory in order to receive antenatal care. This study illustrates dissonance between global expectations and local realities of the delivery of HIV-testing interventions.     

Urban–rural differences in parental Internet mediation and adolescents’ Internet risks in Taiwan

With the development of electronic technology and forms of communication such as the Internet, it has become increasing difficult for parents to identify and mitigate the new risks to which their adolescent children are exposed. In this article, we compare the ways parents and adolescents living in urban areas use the Internet with those of their counterparts who live in rural areas. We based this comparison on data obtained from a survey of Internet use in Taiwan in 2013. The survey included 1079 junior high school students and 688 parents who lived in urban areas and 838 students and 729 parents who lived in rural areas. We found that parents living in rural areas had lower levels of Internet skills and intervened less in their children’s use of the Internet when compared with parents living in urban areas. We also found that, compared with their urban counterparts, adolescents who live in rural areas have lower levels of Internet literacy but a higher frequency of Internet use and they also engage in riskier online behaviours such as online game playing, from which they more often report harmful effects such as the theft of passwords or money. Our multivariate analysis of the data showed that increased levels of adolescents’ online gaming time and lower levels of parental restrictive mediation were associated with higher levels of harm such as the theft of passwords and money stolen online. We also found that lower levels of adolescents’ Internet literacy and lower levels of parental monitoring activity were associated with increases in adolescents’ cyberbullying victimisation. Overall, we found a clear difference between rural and urban parents and adolescents with both rural parents and their children being less experienced and knowledgeable of the risks associated with use of the Internet. Rural children are exposed to more risk and experience more harm.     

Does living in rural areas make a difference for health in Québec?

This study offers an overview of the health status of rural populations and its major determinants in Québec. A wide range of indicators are examined along a spatial grid that allows rural-urban as well as intrarural comparisons. Differences between urban and rural populations mainly concern specific health problems and determinants, while notable variations on these are noted within rural areas. Some avenues for further research and public health policies in Québec are presented.     

Malaria in southern Mozambique: incidence of clinical malaria in children living in a rural community in Manhiça district

We estimated the incidence of clinical malaria episodes by weekly home-based active case detection between December 1996 and July 1999 in 2 groups of children in Manhi?a district in southern Mozambique. Cohort 1 comprised a random sample of children aged <10 years at recruitment and cohort 2 comprised newborns. A blood slide was taken if the axillary temperature was 7.5 degrees C or if the child was reported to have been febrile over the previous 24 h. A total of 1966 children were followed-up. Malaria occurred all year round. The number of clinical malaria episodes ranged from 0 to 6 per child. No clinical malaria episodes were detected in 71% of children or in children aged <2 months. Those aged 6 months to <4 years showed the highest incidence ranging from 0.65 to 0.74 episodes per 100 person-weeks at risk, indicating that infants and young children were at highest risk. Malaria transmission is perennial in this district of Mozambique with some seasonality. Significant differences were observed in the spatial incidence of malaria episodes in regions just a few miles apart with a higher incidence in children living near the river or in swampy areas. These findings strengthen the need for improved control measures targeted at infancy and early childhood.
