2. INTRODUCTION
1. Non-communicable diseases (Burden) :
• Increasing prevalence of NCD deaths
• 52 million deaths by 2030
2. Unhealthy dietary practices, sedentary lifestyle and obesity
3. Nations’ economic, demographic and nutrition transition
4. Studies from western countries on diet and levels of physical
activity in population
5. Limited information available

3. OBJECTIVE
• Study planned to document urban rural differences in dietary
practices, levels of physical activity and obesity in a North
Indian state of Punjab.

9. PARAMETERS STUDIED
1. Socio-demographic profile and
Behavioural information (Tobacco and alcohol use, diet, physical
activity, H/O chronic diseases, family H/O chronic conditions, health
screening and health care costs)
2. Physical measurements
a) Weight: SECA electronic weighing scale to nearest 100g
b) Height: SECA adult portable stadiometer to the nearest 0.1cm
c) Waist circumference: SECA constant tension tape to the nearest
0.1cm
Midway between the lowest rib margin and the iliac crest
d) BMI: Categorised as normal, overweight and obese

10. PARAMETERS STUDIED..
3. Dietary practices
• 1 serving of vegetable – 1 cup of raw green leafy vegetables / ½
cup of other vegetables (cooked/chopped raw)
• 1 serving of fruit – 1 medium size piece of apple, banana or
orange, ½ cup of chopped, canned fruit / ½ cup of fruit juice

11. PARAMETERS STUDIED..
4. Levels of physical activity
• GPAQ (Global Physical Activity Questionnaire) developed by WHO
• 3 domains – work, transport & during leisure time in a normal
active week
• Activities – vigorous, moderate & light
• Minimum duration of physical activity/week recommended by
WHO → 150 min of moderate intensity physical activity / 75
min of vigorous intensity physical activity
(OR)
Equivalent combination of moderate + vigorous
intensity physical activity at least 600 MET with each activity
performed in bouts of at least 10 min duration

12. PARAMETERS STUDIED..
4. Obesity
• Asian cut off
< 18.5 → Underweight
18.5 – 23 → Normal weight
23 – 27.5 → Pre-obese
> 27.5 → Obese
• WHO cut off
< 18.5 → Underweight
18.5 – 24.9 → Normal weight
25 – 29.9 → Pre-obese / Overweight
30 – 34.9 → Class 1 obesity
35 – 39.9 → Class 2 obesity
> 40 → Class 3 obesity

20. Recommendation Report
Results 1. Unadjusted estimates and, if applicable,
confounder-adjusted estimates and their
precision (eg, 95% confidence interval)

relative risk into absolute risk for a
meaningful time period
Yes
Other results Report other analyses done—eg analyses of
subgroups and interactions, and sensitivity
analyses

21. DISCUSSION
Diet and physical activity:
• Present study - Minimal urban rural differences in dietary habits
and levels of physical activity
• Other studies- Higher physical inactivity in urban areas and poor
intake of fruits and vegetables in the rural areas
• Similar survey conducted in 2005 in India reported 6.8% of overall
inactivity levels
• Recent studies reports 38 to 70% of higher levels of physical
inactivity in India – indicating declining physical activity levels in
recent times

22. DISCUSSION...
Obesity:
• Present study – Urban females had higher proportion of
obesity compared to rural counterparts
• Previous study have highlighted significant urban rural
differences in prevalence of overweight and obesity with
urban dwellers being more overweight and obese

23. DISCUSSION...
Recreational physical activity:
• Current study – 90% of individuals in both urban and rural
areas reports no physical activity during leisure time
• Other studies in India and Vietnam – inactivity in the
recreational domain to be as high as 90%

24. RECOMMENDATIONS
Multi-pronged strategic approach :
• For promoting healthy diet
• Restricting the use of unhealthy diet
Regulations to control the content of salt, sugar, saturated fats
and trans fats in dietary products

25. STRENGHTS
• Multi-stage stratified sampling approach
• Involved whole state of Punjab
• Followed standard methodology of STEPS survey

26. LIMITATIONS
• Self-reported survey
• Inherent bias
• Validity- GPAQ
