Assessment of residency and movement of the endangered bullhead (Cottus gobio) in two Flemish rivers

ECOLOGY OF FRESHWATER FISH, Issue 4 2004
G. Knaepkens
Abstract,,, Residency and movement of bullheads (Cottus gobio) were assessed by mark-recapture from November 2001 to June 2002 in two Flemish rivers [Steenputbeek (SPB), Laarse Beek (LB)]. Although the majority of the recaptured bullheads (SPB: 66%; LB: 55%) was found in their initial tagging site before the spawning season, some fish had covered distances between 10,100 m (mean: 17 ± 2 m) and 10,70 m (mean: 18 ± 7 m), respectively. During the spawning season, the proportion of fish that moved (SPB: 58%; LB: 75%) and the distances travelled (SPB: between 10 and 90 m, mean 26 ± 3 m; LB: between 30 and 260 m, mean 133 ± 3 m) were significantly larger. In addition, analysis of individual movement behaviour of multiple recaptured bullheads showed that some fish were either always resident or mobile, while others switched between both behaviours. In general, our results suggest that not all bullheads exhibit sedentary behaviour but that the populations under study consist of both stationary and mobile individuals. Resumen 1. Desde Noviembre del año 2001 hasta Junio del 2002, evaluamos la residencia y los movimientos de Cottus gobio a través de técnicas de marcado-recaptura en dos ríos flamencos: Steenputbeek (SPB) y Laarse Beek (LB). Aunque antes de la estación reproductiva, la mayoría de los individuos re-capturados (66% en SPB y 55% en LB) fueron encontrados en las mismas localidades de marcado, algunos peces habían cubierto distancias entre 10 y 100 metros (media = 17.2 ± 2 m) y entre 10 y 70 m (media = 18.0 ± 7 m) en SPB y LB, respectivamente. Durante la estación reproductiva, tanto la proporción de individuos que se movieron (58% en SPB y 75% en LB), como las distancias recorridas fueron significativamente mayores: en SPB, entre 10 y 90 m, media = 26.0 ± 3 m y en LB entre 30 y 260 m, media = 133.0 ± 3 m. 2. Análisis del comportamiento entre múltiples individuos mostró que algunos individuos fueron o residentes o móviles mientras que otros individuos cambiaron entre ambos comportamientos. En general, nuestros resultados sugieren que no todos los individuos muestran comportamiento sedentario sino que la población incluye individuos estacionarios y móviles. [source]

Weight status, energy-balance behaviours and intentions in 9,12-year-old inner-city children

JOURNAL OF HUMAN NUTRITION & DIETETICS, Issue 1 2010
W. Jansen
Abstract Background:, Dutch youth health care promotes four so-called energy-balance behaviours for the prevention of obesity: increasing physical activity, reducing sedentary behaviour and sugar-containing drinks, and eating breakfast. However, data on the prevalence of these behaviours and intentions to engage in them among primary schoolchildren is limited, especially for multi-ethnic, inner-city populations. The present study aimed to provide these data and explore differences according to socio-demographic characteristics and weight status. Methods:, Data on behaviours and accompanying intentions were collected using classroom questionnaires. Stature and body weight were measured by trained staff. Twenty primary schools in Rotterdam participated. Data on 1095 9,12 year olds (81.7% response rate) were available for analysis. Multiple logistic regression analyses were conducted to determine associations between behaviours (favourable or unfavourable), intentions (positive or not), gender, age, ethnicity, neighbourhood income level and weight status. Results:, The prevalence of being overweight was 30.4%, including 9.0% obesity. Engagement in energy-balance behaviours varied from 58.6% for outdoor play (>1 h previous day) to 85.9% for active transportation to school (day of survey). The highest positive intentions were reported for taking part in sports (83.9%), and lowest for reducing computer time (41.3%). Small differences in behaviours and intentions according to socio-demographic characteristics were found, most notably a lower engagement in physical activity by girls. Skipping breakfast and total number of energy-balance behaviours were associated with being overweight. Conclusions:, The prevalence of being overweight among Dutch inner-city schoolchildren is high. A general rather than a differentiated approach is needed to improve engagement in energy-balance behaviours among inner-city schoolchildren. [source]

Weight control and physical activity in cancer prevention

OBESITY REVIEWS, Issue 1 2002
Franca Bianchini
Summary Overweight and obesity have reached epidemic dimensions worldwide, mainly due to consumption of high energy diets and increased sedentary behaviour. Overweight and insufficient physical activity are clearly associated with cardiovascular diseases and type 2 diabetes. Evidence is also accumulating that they may also increase cancer risk, particularly in the colon, breast and endometrium. This effect seems to be mediated by alterations in the metabolism of endogenous hormones, including sex steroids and insulin, and levels of insulin-like growth factor(IGF)-I and IGF-binding proteins. In light of the beneficial effects of weight control and physical activity for cancer prevention, a healthy lifestyle, keeping a low body weight and exercising most days of the week, is recommended.

Early sexual debut and associated factors among in-school adolescents in eight African countries

ACTA PAEDIATRICA, Issue 8 2010
Karl PeltzerArticle first published online: 19 MAY 2010
Abstract Objective:, This report examines early sexual debut (sedentary behaviour, having been in a physical fight and seriously injured, while for girls, mental distress and poor economic status and for boys, bullied and poor parental or guardian supervision were associated with early coital debut. In multivariable analysis, early sexual debut was among boys associated with currently smoking (OR = 4.45, p = 0.002) and truancy (OR = 2.02, p = 0.007) and, among girls, associated with lower education (OR = 0.22, p = 0.004), ever drunk (OR = 3.94, p = 0.016), having no close friends (OR = 3.36, p = 0.014) and poor parental connectedness (OR = 2.43, p = 0.037). Conclusion:, The study found a high prevalence of early sexual debut among 15-year-olds in eight African countries. Risk factors identified were consistent with problem behaviour theory in which early onset of adolescent sexual behaviour is shared with other problem behaviours. Prevention programmes should broaden sexual health promotion including problem behaviour such as substance use and mental distress for boys and girls in the preteen years, before sexual debut.

Physical activity to prevent obesity in young children: cluster randomised controlled trial . Reilly, J. J., Kelly, L., Montgomery, C., Williamson, A., Fisher, A., McColl, J. H., Lo Conte, R., Paton, J. Y. & Grant, S. ( 2006 ) British Medical Journal , 333 , 1041 DOI: 10.1136/bmj.38979.623773.55. Objective To assess whether a physical activity intervention reduces body mass index in young children. Design Cluster randomized controlled single blinded trial over 12 months. Setting Thirty-six nurseries in Glasgow, Scotland. Participants In total, 545 children in their pre-school year, mean age 4.2 years (SD 0.2) at baseline. Intervention Enhanced physical activity programme in nursery (three 30-minute sessions a week over 24 weeks) plus home-based health education aimed at increasing physical activity through play and reducing sedentary behaviour. Main outcome measure Body mass index, expressed as a standard deviation score relative to UK 1990 reference data. Secondary measures were objectively measured physical activity and sedentary behaviour; fundamental movement skills; and evaluation of the process. Results Group allocation had no significant effect on the primary outcome measure at 6 and 12 months or on measures of physical activity and sedentary behaviour by accelerometry. Children in the intervention group had significantly higher performance in movement skills tests than control children at 6-month follow-up (P = 0.0027; 95% CI 0.3,1.3) after adjustment for sex and baseline performance. Conclusions Physical activity can significantly improve motor skills but did not reduce body mass index in young children in this trial. [source]
