Patterns of physical activity for adolescent girls in Fiji and Tonga

Behavioural patterns are determined in part by sociocultural factors such as values, expected behaviours and sociopolitical organisation. This paper presents the patterns of physical activity reported by Tongan and Fijian females aged 12-18 years and possible explanations for these patterns. The paper draws on interviews conducted in a wider study of adolescents patterns of eating, physical activity and body size in Tonga, Fiji, New Zealand and Australia. The study examined sociocultural factors that could promote or protect against obesity from the perspective of adolescents in order to develop culturally-appropriate strategies for healthy lifestyles. Twenty four indigenous Fijian and 24 Tongan females aged 12-18 years were interviewed by females who were fluent in participants first languages. Researchers from Australia, Tonga and Fiji analysed the data separately and then together in order to capture cultural nuances and enhance cultural validity. This analysis revealed similarities and differences in both cultural groups. Limitations to physical activity identified by Tongan and Fijian girls included the time spent in household chores and parental restrictions.Fijian girls also identified concern about personal safety as a constraint. These findings are examined in relation to sociocultural factors that appear to limit opportunities for young females to be physically active.

A comparison of the socio-cultural influences on body size perceptions and values among European Australian and Indigenous Fijian adolescent girls

Western women are experiencing increases in the prevalence of overweight and obesity despite valuing slimness as ideal and equating thinness with attractiveness and beauty. Pacific populations are also experiencing high prevalence rates of overweight and obesity. A lage body size, however, has many positive connotations among pacific populations that stem from rich cultural practices such as feasts and deliberate fattening of women. There appears to be many sociocultural factors however, such as images of the slim ideal portrayed in Western media, influencing body image concerns that are shared between the two groups. A qualitative study involving semi-structured interviews was conducted to examine and compare the sociocultural influences on body size perceptionsand values. Participants include 16 European Australian and 16 Indigenous Fijian adolescent girls aged between 15 and 17 years. Inductive thematic analysis and analytical induction were qualitativemethods employed to facilitate interpretation of the findings. Preliminary findings suggest that Fijian adolescent girls experience greater conflict than European Australian girls about the desired body size endorsed in their community. Results also suggest that Indigenous Fijian girls place less importance than Australian girls on manipulating their body to achieve a specific ideal. Specific results of this study are reviewed and recommendations for future research are discussed.

Motivational interviewing and cognitive behaviour therapy in the treatment of adolescent overweight and obesity : study design and methodology

Background

Despite the high prevalence and negative physical and psychosocial consequences of overweight and obesity in adolescents, very little research has evaluated treatment in this population. Consequently, clinicians working with overweight and obese adolescents have little empirical research on which to base their practise. Cognitive behavioural therapy has demonstrated efficacy in promoting behaviour change in many treatment resistant disorders. Motivational interviewing has been used to increase motivation for change and improve treatment outcomes. In this paper we describe the rationale and design of a randomised controlled trial testing the efficacy of motivational interviewing and cognitive behaviour therapy in the treatment of overweight and obese adolescents.
Methods

Participants took part in a motivational interview or a standard semi-structured assessment interview and were then randomly allocated to a cognitive behavioural intervention or a wait-list control condition. The cognitive behavioural intervention, the CHOOSE HEALTH Program, consisted of 13 individual treatment sessions (12 face-to-face, 1 phone call) followed by 9 maintenance sessions (7 phone calls, 2 face-to-face). Assessments were conducted prior to participation, after the treatment phase and after the maintenance phase of intervention. Improvement in body composition was the primary outcome; secondary outcomes included improved cardiovascular fitness, eating and physical activity habits, family and psychosocial functioning.
Conclusion

Despite the demonstrated effectiveness of motivational interviewing and cognitive behavioural therapy in the long-term management of many treatment resistant disorders, these approaches have been under-utilised in adolescent overweight and obesity treatment. This study provides baseline data and a thorough review of the study design and treatment approach to allow for the assessment of the efficacy of motivational interviewing and cognitive behavioural therapy in the treatment of adolescent overweight and obesity. Data obtained in this study will also provide much needed information about the behavioural and psychosocial factors associated with adolescent overweight and obesity.

The development of young adolescent boys' weight and shape concerns

This thesis' longitudinal study found that young adolescent boys' reported significant concerns with their weight and shape, particularly with respect to having a more muscular but lean physique. The strongest predictors of high body dissatisfaction, among boys, were poor perceptions of their sporting ability and low self-esteem. The portfolio examines the use of Single Session Therapy (SST) suggesting that SST can effectively reduce waiting lists and provide a single and complete intervention that is effective in approximately 50% of cases.
