Transcript of "EHLE Perception Analysis"

  1. 1. Dr. Laura MC Welschen Preliminary results perception analysis Prof. dr. Giel Nijpels, Prof. dr. Henriette van der Horst
  2. 2. The idea <ul><li>4 x 300 questionnaires  many data  worthwile to write a paper for a scientific journal </li></ul><ul><li>Research question: </li></ul><ul><li>What are the differences in reported health behaviour between the northern and southern European countries? </li></ul>
  3. 3. Background: literature <ul><li>Example: type 2 diabetes mellitus (T2DM) </li></ul><ul><li>Prevalence of T2DM differs between European countries </li></ul><ul><li>Cause: no impact of age and BMI </li></ul><ul><li>But what is the cause? </li></ul><ul><ul><li>Differences in genetic disposition? </li></ul></ul><ul><ul><li>Differences in lifestyle?  EHLE data </li></ul></ul><ul><li> Other examples with a variance in prevalence: cancer, cardiovascular disease etc. </li></ul>
  4. 4. Differences in physical activity Italy Spain France The Netherlands
  5. 5. Differences in diet Italy Spain France The Netherlands
  6. 6. Methods <ul><li>Study population: 4 x 300 people </li></ul><ul><li>Dependent variable = health behaviour: smoking, physical activity, nutrition, alcohol consumption. </li></ul><ul><li>Independent variable = degree of latitude: gives the location of a place on earth north or south of the equator </li></ul>
  7. 7. Degrees of latitude Netherlands = 52.31° France = 50.64° Italy = 45.41 ° Spain = 38.36 °
  8. 8. Methods <ul><li>Multivariate regression analysis: </li></ul><ul><li>assess differences in reported health behaviour between the northern and southern European countries. </li></ul><ul><li> behaviour: focus on lifestyle: </li></ul><ul><li>physical activity, smoking, nutrition, alcohol </li></ul><ul><li> data adjustment for age, sex, level of education, living situation (alone or together) </li></ul>
  9. 9. Characteristics Netherlands France Italy Spain Age (years) 63.2 76.1 70.0 66.6 Sex (% men) 52.2 28.5 42.5 37.7 Living situation (% alone) 16.2 63.5 22.6 26.0 Level of educa-tion (%) Primary 22.6 54.8 31.7 15.5 Secondary 44.9 36.6 32.8 37.7 University 24.7 4.5 10.3 43.1 Other 7.8 4.1 25.2 3.7
  10. 10. Differences in physical activity (1)
  11. 11. Differences in physical activity (2) Spain = reference category (most southern country) Odds ratio: chance of performing more than 3 days of physical activity * Significant different (p < 0.05) NL France Italy Spain Model 1: crude 0.83 0.53 * 0.24 * 1.0 Model 2: Age, sex 0.84 0.49 * 0.22 * 1.0 Model 3: Level of education 0.81 0.50 * 0.23 * 1.0 Model 4: Living alone/together 0.83 0.54 * 0.24 * 1.0
  12. 12. Differences in smoking behaviour (1)
  13. 13. Differences in smoking behaviour (2) Spain = reference category (most southern country) Odds Ratio: chance of smoking * Significant different (p < 0.05) NL France Italy Spain Model 1: crude 0.94 0.36 * 1.27 1.0 Model 2: Age, sex 0.74 0.57 1.35 1.0 Model 3: Level of education 0.98 0.48 * 1.52 1.0 Model 4: Living alone/together 0.93 0.32 * 1.31 1.0
  14. 14. Differences in nutrition (1)
  15. 15. Differences in nutrition (2)
  16. 16. Differences in alcohol consumption (1) Spain = reference category (most southern country) Category ‘never’ = reference category Odds Ratio: chance of drinking alcohol Significant different (p<0.05), even after data adjustment
  17. 17. Differences in alcohol consumption (2) Significant different (p<0.05), even after data adjustment Spain = reference category Category ‘never’ = reference category
  18. 18. Summary <ul><li>Physical activity : Italy and France perform less physical activity </li></ul><ul><li>Smoking : France has less smokers </li></ul><ul><li>Nutrition : </li></ul><ul><li>Spain eats more fruit </li></ul><ul><li>France eats less vegetables </li></ul><ul><li>The Netherlands eats more bread </li></ul><ul><li>Spain and the Netherlands use more dairy products </li></ul><ul><li>Spain prefers fish above meat </li></ul><ul><li>Alcohol: </li></ul><ul><li>Spain and the Netherlands are beer drinkers </li></ul><ul><li>Italy and France are wine drinkers </li></ul>
  19. 19. Conclusion <ul><li>There are differences between the countries </li></ul><ul><li>However, no northern – southern effect </li></ul><ul><li>- Effects have been adjusted for confounding (age, sex. Level of education, living situation) but these variables did not influence the results </li></ul><ul><li>Attention to selection bias: people that were recruited to fill in questionnaires </li></ul>
  20. 20. Further possible analyses <ul><li>* Assessment of differences between the northern and southern countries in : </li></ul><ul><li>Medication </li></ul><ul><li>Emotional health </li></ul><ul><li>Memory status </li></ul><ul><li>* Other research questions: </li></ul><ul><li>- Is health behaviour associated with general health and emotional health? </li></ul>
