IntroductionIntroduction• The influence of smoking, diet, physical activity and
alcohol consumption, on health is well documented
• Individual lifestyle focus to date
• 4 Positive Lifestyle Behaviours (Khaw et al)– 5+ Fruit and vegetables– Non-smoker– Being physically active – Being a moderate drinker
• Combined – predict a 4-fold difference in total mortality in men and women,
thus demonstrating that even small differences in lifestyle may make a big difference to the health of the population

SLÁN 2007 PLB ScoreSLÁN 2007 PLB Score
• Participants scored one point for each of the following health behaviours: – being a current non smoker; – being physically active (moderate/high activity score); – being a moderate drinker (1-14 alcohol units per
week); and– consuming 5 or more servings of fruit and vegetables
daily.
• Participants could score from zero to four protective lifestyle behaviours (PLBs)

Protective Lifestyle FactorsProtective Lifestyle Factors• Sixteen percent scored 4 PLBs, 35% reported 3 PLBs, 32% 2 PBLs ,
15% scored 1 and 2% zero
• Men, older respondents and respondents in social classes 5-6 reported practising fewer PLBs compared to their respective counterparts

Self Rated General Health and PLBSelf Rated General Health and PLB
• Self rated health is worse among those demonstrating fewer protective lifestyle behaviours – Respondents with zero protective behaviours were
more likely to report their health as fair or poor rather than excellent/very good/good compared to those who had one or more protective behaviours.
– Those who scored zero for health behaviours had five times the odds of rating their general health as ‘fair or poor’ those with a score of 4.

Obesity and PLBObesity and PLB• A significant trend existed between BMI and PLB score (p<0.001). The odds
of being overweight or obese increased as PLB score decreased (OR 1.491 95% CI [.994-2.235] for 0 v’s 4PLBs).

ConclusionsConclusions• We face a surmountable battle to address the
‘causes of the causes’ of cardiovascular disease
• Data on the prevalence of core protective behaviours will provide an important population health metric to guide public policy over the next decade.
• Specifically highlights the need to develop a holistic approach to population health
