Overweight and obesity (25-79 years), self-reported, by educational attainment (NH)

Description

Proportion of survey respondants who are overweight or obese. Based on self-reported height and weight.

The following questions have been included in Statistics Norway's survey of level of living, health conditions since 1998:
- How tall are you, without shoes?
- How much do you weigh, without clothes or shoes? (for pregnant women, ask about their weight prior to pregnancy)

Body mass index (BMI) is calculated as body weight (kg) divided by height (m) squared. BMI is then classified according to WHO's definitions for the adult population:
- BMI 25.0-29.9: overweight
- BMI 30.0+: obese


For children and young people under 18 years IOTF's age- and gender-specific threshold values are used to classify overweight and obesity. These values are used to calculate the proportion of overweightfor thos younger than 18 years

Kind of Data

Statistics based on fewer than 3 cases is hidden to protect the identity of the patients. Figures are also hidden when the population group in which the cases originate, is smaller than 30 persons.

If more than 20 per cent of the cases in a time series are hidden due to the abovementioned reasons, the complete time series is hidden to avoid giving a skewed impression.
The complete time series is also hidden if more than 50 per cent of the values in the series are based on fewer than 10 cases. In this case, the figures are regarded as too uncertain.

Frequency of updates

Every 3-4 years

Collection

Data is collected every 3-4 years from Statistics Norway's survey of level of living. A nationally representative sample of 10 000 individuals is drawn, with around 7 000 completing the survey via a personal or telephone interview. Survey participants are required to assess their own health, illness, disability, living habits and utility of health services. People living in institutions are not included. Each survey provides an indication of the population's health at a given point in time (cross-sectional survey). Repition of the survey provides an indication of developments in health over time. Nationally representative data.

Data quality

The health survey is a stable and regular source of data about different aspects of the population's health. In recent years, the survey has had a stable participation rate of around 60%, which is good compared with other health surveys in Norway. The questions concerning overweight and obesity have remained unchanged and is comparable over time.

Restrictions

Overweight and obesity increase the risk of type 2 diabetes, cardiovascular disease, hypertension, osteoarthritis of the knees and hips and some cancers such as colon cancer. Overweight and obesity can also have serious mental health consequences. There is no clear BMI threshold for when disease risks increases or decreases, the transitions are sliding.

Experience shows that for most people it is difficult to achieve lasting weight loss once you've been overweight. Prevention of obesity is therefore of great importance. Measures that can affect food and activity habits will be of particular importance.
