Study Notes
Prevalence of Overweight and Obesity
- In 2021, the prevalence of overweight and obesity among women was 59.0%, while for men, it was 68.6%.
- Data from 2021 is not directly comparable to previous years.
Food Insecurity
- Food insecurity affects over one-third of adults limited by disability (38%) compared to 13% in households without such limitations.
- Non-white ethnic groups face a higher risk of food insecurity (33.5%) than white ethnic groups (17%).
Contributors to Obesity
- Obesity's causes are multifaceted, including:
- Psychological factors
- Endocrine disorders
- Psychiatric disorders
- Medication side effects
- Genetic predispositions
- Cultural influences
- Environmental and social factors
Consequences of Obesity
- Obesity is a modifiable risk factor for several serious health conditions, including:
- Cancer
- Osteoarthritis
- Stroke
- Poor mental health
- Infertility
- Cardiovascular disease
- Type 2 diabetes
- Fatty liver disease
- Respiratory problems
- Premature death
Treatment Options for Obesity
- Effective treatments include:
- Lifestyle changes and reduced energy diets
- Increased physical activity
- Pharmacotherapy options, including appetite suppressants and GLP-1 agonists (liraglutide and semaglutide)
- Bariatric surgery options like gastric banding and sleeve gastrectomy
- Emphasis on patient-centered care and shared decision-making
Energy Intake and Expenditure
- Energy intake (EI) refers to the calories consumed, including macronutrients (fat, carbohydrate, protein, alcohol).
- Energy expenditure (EE) measures the body’s energy usage, comprising basal metabolic rate and energy used during physical activity.
- A positive energy balance (weight gain) occurs when EI exceeds EE.
Definition of Overweight and Obesity
- Overweight and obesity are defined as excessive fat accumulation posing health risks by the WHO.
- Body Mass Index (BMI) classifications:
- Underweight: BMI < 18.5
- Normal: BMI 18.5-24.9
- Overweight: BMI 25-29.9
- Obese: BMI 30-39.9
- Morbidly obese: BMI ≥ 40
- BMI may be inaccurate for muscular individuals and varies by ethnic background.
Implications of Weight Stigma
- Only 26% of people with obesity feel respected when seeking medical advice.
- 42% feel uncomfortable discussing weight-related issues with their GP.
- Weight stigma can exacerbate unhealthy eating behaviors.
Malnutrition Statistics and Impact
- The financial burden of malnutrition in the UK health and social care system exceeds £23 billion annually.
- High malnutrition risk among those living at home (56%), with 44% of hospitalized patients and 55% in care homes being at risk.
Screening for Malnutrition
- The Malnutrition Universal Screening Tool (MUST) is a five-step process developed to identify adults at risk and formulate care plans.
- MUST encompasses various assessment parameters, including anthropometry, biochemistry, clinical evaluations, and dietary considerations.
