Prevention of ill health - obesity

Inquiry5

The Health and Social Care Committee held an inquiry into the prevention of ill health – obesity.

Background

Obesity is recognised as one of the most significant public health challenges, both in the UK and internationally. Prevalence is rising in Wales (as elsewhere), with much higher levels of obesity in the most disadvantaged communities.

Obesity is a key risk factor for a wide range of chronic diseases, including type 2 diabetes, hypertension, cardiovascular disease (including stroke), and some cancers. It also impacts people’s wellbeing, quality of life, and ability to work.

Public Health Wales has previously estimated the cost of obesity to the NHS in Wales as £73m. By 2050, this is estimated to rise to £465m. The broader cost to society and the economy in Wales by 2050 is estimated at £2.4bn.  

The promotion of healthy lifestyles and prevention is one of the priority issues identified in the Committee’s strategy for the Sixth Senedd. As such, the Committee would welcome your views on the following terms of reference;

The effectiveness of Welsh Government strategy, regulations, and associated actions to prevent and reduce obesity in Wales, including consideration of:

>>>> 

>>>gaps/areas for improvement in existing policy and the current regulatory framework (including in relation to food/nutrition and physical activity);

>>>the impact of social and commercial determinants on obesity;

>>>interventions in pregnancy and early childhood to promote good nutrition and prevent obesity;

>>>the stigma and discrimination experienced by people who are overweight/obese;

>>>people’s ability to access appropriate support and treatment services for obesity;

>>>the relationship between obesity and mental health;

>>>international examples of success (including potential applicability to the Welsh context).
