Abstract [en]

BACKGROUND: The use of tobacco products among adolescents in Southeast Asia represents a major public health burden. Two out of ten adolescents attending school are tobacco users and several factors influence them to initiate tobacco use. Most studies related to tobacco use are quantitative, whereas qualitative studies exploring adolescents' smoking behavior and their views, knowledge and experiences are scarce.

OBJECTIVE: To gain a deep understanding of Nepalese adolescents' knowledge and opinions about smoking and reasons for smoking initiation.

SUBJECTS: Adolescents from four secondary schools in the Bhaktapur district, Nepal.

METHODS: Eight focus-group discussions were conducted with 71 adolescents aged 13-16 years and from grades 8-10. Data were analyzed using manifest qualitative content analysis.

RESULTS: The participants knew that smoking represents health risks as well as socio-economic risks, but few described the addictive nature of tobacco and health risks related to passive smoking. Most participants related smoking initiation to the smoking behavior of peers and family members, but easy accessibility to cigarettes, ineffective rules and regulations, and exposure to passive smoking also created environments for smoking. Some expressed confidence to resist peer pressure and refuse to start smoking, but also expressed the need for prevention strategies in schools and for governmental initiatives, such as more strict implementation of tobacco control and regulations to prevent and reduce smoking.

CONCLUSION: Curbing the tobacco epidemic in Nepal requires healthy public policies and multifaceted interventions to address the knowledge gap on health consequences associated with smoking among adolescents, teachers and parents/adults.

Abstract [en]

Skilled birth attendant (SBA) utilization is low in remote and rural areas of Nepal. We designed and implemented an evaluation to assess the effectiveness of a five-component intervention that addressed previously identified barriers to SBA services in mid- and far-western Nepal. We randomly and equally allocated 36 village development committees with low SBA utilization among 1-year intervention and control groups. The eligible participants for the survey were women that had delivered a baby within the past 12 months preceding the survey. Implementation was administered by trained health volunteers, youth groups, mothers' groups and health facility management committee members. Post-intervention, we used difference-in-differences and mixed-effects regression models to assess and analyse any increase in the utilization of skilled birth care and antenatal care (ANC) services. All analyses were done by intention to treat. Our trial registration number was ISRCTN78892490 (http://www.isrctn.com/ISRCTN78892490). Interviewees included 1746 and 2098 eligible women in the intervention and control groups, respectively. The 1-year intervention was effective in increasing the use of skilled birth care services (OR = 1.57; CI 1.19-2.08); however, the intervention had no effect on the utilization of ANC services. Expanding the intervention with modifications, e.g. mobilizing more active and stable community groups, ensuring adequate human resources and improving quality of services as well as longer or repeated interventions will help achieve greater effect in increasing the utilization of SBA.

Abstract [en]

Objectives: The aim of this study was to examine age- and gender-related patterns of PA and depressive symptoms among students through their adolescent years. Design: Data from three population-based surveys were analysed to determine levels of moderate- to vigorous-intensity PA (MVPA), participation in organized sports and depressive symptoms among 10-19-year-old adolescents. Method: Questionnaires assessing PA and depressive symptoms were administered to 32 860 students in compulsory and upper-secondary schools in Iceland. Results: As age increased, depressive symptoms increased and PA decreased with over half of the adolescents in upper-secondary schools not achieving recommended daily PA. There were gender differences in PA and depressive symptoms with girls being less active and reporting higher levels of depressive symptoms than boys. MVPA was associated with lower levels of depressive symptoms among both genders while organized sports had more impact on depressive symptoms among girls. Conclusions: To our knowledge, this study is the first to simultaneously examine patterns of PA and depressive symptoms among students through their adolescent years. Our findings show that the decrease in PA and increase in depressive symptoms is most pronounced around the transition from compulsory to upper-secondary school, or around the age of 15-16. Thus the findings provide important information about when to tailor public health efforts to reduce the burden of depressive symptoms among adolescents, for example by employing PA interventions.

Abstract [en]

The aim of our study was to assess associations between smoking behavior before and during pregnancy and selected adverse birth outcomes. This study is based on the Murmansk County Birth Registry (MCBR). Our study includes women who delivered a singleton pregnancy after 37 weeks of gestation (N = 44,486). Smoking information was self-reported and assessed at the first antenatal visit during pregnancy. We adjusted for potential confounders using logistic regression. The highest proportion of infants with low values of birth weight, birth length, head circumference, ponderal index and of the Apgar score at 5 min was observed for women who smoked both before and during pregnancy. We observed a dose-response relationship between the number of cigarettes smoked per day during pregnancy and the odds of the aforementioned adverse birth outcomes; neither were there significant differences in their occurrences among non-smokers and those who smoked before but not during pregnancy. Moreover, smoking reduction during pregnancy relative to its pre-gestation level did not influence the odds of the adverse birth outcomes. Our findings emphasize a continued need for action against tobacco smoking during pregnancy.

Abstract [en]

BACKGROUND: Although prior studies have shown that smoking reduces preeclampsia/eclampsia risk, the consequence of giving up this habit during pregnancy should be assessed. The aims of the current study were threefold: (i) describe maternal characteristics of women with preeclampsia/eclampsia; (ii) examine a possible association between the number of cigarettes smoked daily during pregnancy and the development of this affliction; and (iii) determine if first-trimester discontinuation of smoking during pregnancy influences the risk.

METHODS: A registry-based study was conducted using data from the Murmansk County Birth Registry (MCBR). It included women without pre-existing hypertension, who delivered a singleton infant during 2006-2011 and had attended the first antenatal visit before 12 week of gestation. We adjusted for potential confounders using logistic regression.

RESULTS: The prevalence of preeclampsia/eclampsia was 8.3% (95%CI: 8.0-8.6). Preeclampsia/eclampsia associated with maternal age, education, marital status, parity, excessive weight gain and body mass index at the first antenatal visit. There was a dose-response relationship between the number of smoked cigarettes per day during pregnancy and the risk of preeclampsia/eclampsia (adjusted OR1-5 cig/day = 0.69 with 95%CI: 0.56-0.87; OR6-10 cig/day = 0.65 with 95%CI: 0.51-0.82; and OR≥11 cig/day = 0.49 with 95%CI: 0.30-0.81). There was no difference in this risk among women who smoked before and during pregnancy and those who did so before but not during pregnancy (adjusted OR = 1.10 with 95%CI: 0.91-1.32).

CONCLUSIONS: Preeclampsia/eclampsia was associated with maternal age, education, marital status, parity, excessive weight gain, and body mass index at the first antenatal visit. There was a negative dose-response relationship between the number of smoked cigarettes per day during pregnancy and the odds of preeclampsia/eclampsia. However, women who gave up smoking during the first trimester of gestation had the same risk of preeclampsia/eclampsia as those who smoked while pregnant. Consequently, antenatal clinic specialists are advised to take these various observations into account when counselling women on smoking cessation during pregnancy.

Abstract [en]

BACKGROUND: The aim of this pilot study was to examine the impact of a brief physical activity intervention on adolescents' subjective sleep quality. Cross-sectional studies indicate that physically active adolescents have better subjective sleep quality than those with more sedentary habits. However, less is known about the effectiveness of physical activity interventions in improving adolescents' subjective sleep quality.

METHODS: In a three-week physical activity intervention, four Icelandic upper secondary schools were randomized to either an intervention group with pedometers and step diaries or a control group without pedometers and diaries. Out of 84, a total of 53 students, aged 15-16 years, provided complete data or a minimum of two days step data (out of three possible) as well as sleep quality measures at baseline and follow-up. Subjective sleep quality, the primary outcome in this study, was assessed with four individual items: sleep onset latency, nightly awakenings, general sleep quality, and sleep sufficiency. Daily steps were assessed with Yamax CW-701 pedometers.

RESULTS: The intervention group (n = 26) had significantly higher average step-count (p = 0.03, partial η(2) = 0.093) compared to the control group (n = 27) at follow-up. Subjective sleep quality improved (p = 0.02, partial η(2) = 0.203) over time in the intervention group but not in the control group.

CONCLUSIONS: Brief physical activity interventions based on pedometers and step diaries may be effective in improving adolescents' subjective sleep quality. This has important public health relevance as the intervention can easily be disseminated and incorporated into school curricula.

Abstract [en]

BACKGROUND: Though cardiovascular diseases are mostly seen in adulthood, the foundation of diet and physical activity is largely formed during childhood. The study aimed to explore children's preference for diet and physical activity in a peri-urban area of Nepal because this is an important dimension to explore in the life-course approach to combat non-communicable diseases.

METHODS: We conducted a cross-sectional study to enquire young peri-urban children of Duwakot and Jhaukhel villages of Bhaktapur district, Nepal on their preferences for diet and physical activity. All eligible households with children in the age range 5-10 years as enlisted from the Jhaukhel-Duwakot Health Demographic Surveillance Site database were selected for the study. Twelve enumerators visited the selected households and facilitated the eligible children to fill in the questionnaire. We used a child-friendly photo-assisted questionnaire with face-scales that easily enabled the children to select a particular preference for each of the food item and physical activity. During analysis, food items were categorized into 'green', 'yellow' and 'red' on the basis of their nutritive values. Physical activity was categorized based on severity of the activity.

RESULTS: Four hundred and thirty seven children filled up the questionnaires. Overall, median preference scores for 'red' food were higher than for healthier 'green' food (4.16 vs. 4.03), particularly, if mothers were self-employed. Likewise, the children preferred low over moderate-to-severe physical activity (4.16 vs. 3.50), and preference was affected by parents' occupation and income.

CONCLUSIONS: The study objectively revealed that most of the children preferred unhealthier food-items and low physical activities. It shall be useful to consider these findings while planning health promotional activities targeted at them.

Abstract [en]

BACKGROUND: Factors contributing to perinatal mortality (PM) in Northwest Russia remain unclear. This study investigated possible associations between selected maternal and fetal characteristics and PM based on data from the population-based Murmansk County Birth Registry.

OBJECTIVE: This study investigated possible associations between selected maternal and fetal characteristics and PM based on data from the population-based Murmansk County Birth Registry.

METHODS: The study population consisted of all live- and stillbirths registered in the Murmansk County Birth Registry during 2006-2011 (n = 52,806). We excluded multiple births, births prior to 22 and after 45 completed weeks of gestation, infants with congenital malformations, and births with missing information regarding gestational age (a total of n = 3,666) and/or the studied characteristics (n = 2,356). Possible associations between maternal socio-demographic and lifestyle characteristics, maternal pre-pregnancy characteristics, pregnancy characteristics, and PM were studied by multivariable logistic regression. Crude and adjusted odds ratios with 95% confidence intervals were calculated.

RESULTS: Of the 49,140 births eligible for prevalence analysis, 338 were identified as perinatal deaths (6.9 per 1,000 births). After adjustment for other factors, maternal low education level, prior preterm delivery, spontaneous or induced abortions, antepartum hemorrhage, antenatally detected or suspected fetal growth retardation, and alcohol abuse during pregnancy all significantly increased the risk of PM. We observed a higher risk of PM in unmarried women, as well as overweight or obese mothers. Maternal underweight reduced the risk of PM.

CONCLUSIONS: Our results suggest that both social and medical factors are important correlates of perinatal mortality in Northwest Russia.
