Abstract(s)
Introdução: A obesidade e o excesso de peso são um problema de saúde pública com impacto a nível mundial. Em 2015, 32% e 33.2% das mulheres e 25% e 45.5% dos homens, residentes em Portugal tinham obesidade e excesso de peso, respetivamente. Estes números impactuam a saúde física e mental, sendo o trabalho nesta área crucial. O presente estudo teve como objetivo explorar as estratégias de início e manutenção da perda de peso bem-sucedida, numa amostra de adultos portugueses, com o recurso a duas taxonomias de mudança comportamental (BCT’s e OxFAB). Método: A amostra do estudo foi composta por 57 participantes entre os 20-66 anos (M=41.96; DP=13.06). Os participantes do estudo tinham um IMC entre 21.64-29.70 kg/m2 (DP=2.32). Os dados foram recolhidos através de entrevistas semiestruturadas gravadas e posteriormente transcritas e analisadas. Resultados: A análise de dados revelou que a estratégia mais mencionada pelos participantes para o início da perda de peso foi o suporte social de um nutricionista (número de menções [NM] = 135; número de participantes [NP] = 42), enquanto a estratégia mais referida na manutenção da perda de peso foi a prática de atividade física regular (NM = 116; NP = 38). Discussão: Os resultados mostram a importância percebida da prática de atividade física e da mudança do comportamento alimentar guiada por uma profissional no alcance de uma perda de peso bem-sucedida. A presença de profissionais no Serviço Nacional de Saúde que trabalhem estes componentes junto de pessoas com obesidade é urgente, considerando a prevalência da mesma.
ABSTRACT: Introduction: Obesity and overweight are a public health issue with a global impact. In 2015, 32% and 33.2% of women and 25% and 45.5% of men living in Portugal were obese or overweight, respectively. These numbers have an impact on physical and mental health, making work in this area is crucial. The present study aimed to explore the strategies for initiating and maintaining successful weight loss, in a sample of Portuguese adults, using two taxonomies of behavioural change (BCT and OxFAB). Method: The study sample comprised 57 participants aged 20-66 years (M=41.96; SD=13.06). The study participants had a BMI between 21.64-29.70 kg/m2 (SD=2.32). Data were collected through semi-structured interviews that were recorded and subsequently transcribed and analysed. Results: Data analysis revealed that the most mentioned strategy by participants for initiating weight loss was social support from nutritionist (number of mentions [NM] = 135; number of participants [NP] = 42), while the most mentioned strategy for maintaining weight loss was reference to regular physical activity (NM = 116; NP = 38). Discussion: The results emphasise the perceived importance of physical activity and dietary behaviour change in achieving successful weight loss. The presence of professionals in the National Health Service who work on these components with people who are obese is urgent, considering the prevalence of obesity.
