Q

What is the most common co-occurring disease with CHD? and why?

A

Diabetes - most likely to have certain conditions or risk factors that increase the chances of having CHD such as high blood pressure or high cholesterol

CHD causes almost 60% of deaths in those with diabetes as they go on to develop these problems because of it

23
Q

How many patients with heart failure were found to have depression?

A

Clinically significant depression was present in at least one in five patients with heart failure

The relationship between depression and poorer heart failure outcomes is consistent and strong across multiple endpoints

24
Q

What have studies found regarding heart attack and social support?

A

Having low social support networks was a predictor of 1-year mortality following acute myocardial infarction

25
Q

What have studies compared low social support to in relation to CVD?

A

They have claimed it to be equivalent to many classic risk factors such as elevated cholesterol levels, tabacco use and hypertension

26
Q

Anger and hostility is another significant predictor of mortality in CHD - how and why?

A

High levels of hostility put individuals at a 58% risk of secondary events

The association was mainly moderated by poor health behaviours, specifically physical inactivity and smoking

27
Q

How are positive psychological attitudes associated with superior cardiac outcomes?

A

Especially optimism!!

Associated with increased participation in cardiac health behaviours (e.g., healthy eating, physical activity) linked to beneficial outcomes

Evidence for direct effect ‐ positive psychological states and biomarkers of cardiac health (e.g., inflammatory markers) is mixed, not as strong

28
Q

Explain planning

A

Is a prospective self‐regulatory strategy, a mental simulation of linking concrete responses to future situations

29
Q

What is action planning?

A

Can help initiate action by specifying when, where
and how to act
Synonymous with implementation intentions

30
Q

What is coping planning?

A

Can help a person to overcome obstacles and cope with difficulties by anticipating situations that put intended behaviour at risk

31
Q

How are action and coping planning beneficial for long term lifestyle change?

A

Study - CHD rehab (needed to adhere to physical activity increase)
Action plans were more influential early in the rehabilitation process, whereas coping plans were more instrumental later on.

People with higher levels of coping planning after discharge were more likely to report higher levels of exercise four months after discharge

32
Q

SMART goals?

A 
Specific
Measurable
Attainable 
Relevant
Time-based
33
Q

What does obesity put you at risk of?

A

It is a major risk for CVD, type 2 diabetes, some musculoskeletal conditions and some cancers

34
Q

What is the most widely used method to measure someones weight?

A

BMI

weight (kg)/height(m squared)

35
Q

What BMI score is considered NORMAL?

A

between 18.5 and 24.9

36
Q

What BMI score is considered OVERWEIGHT?

A

between 25 and 29.9

37
Q

What BMI score is considered OBESE?

A

between 30 and 34.9

38
Q

What BMI score is considered SEVERELY OBESE?

A

between 35 and 39.9

39
Q

What BMI score is considered MORBIDLY OBESE?

A

40+

40
Q

Where is obesity particularly on the rise?

A

Low income countries!

Particularly urban settings

41
Q

In 2014 - how many adults were overweight or obese?

A

1.9 billion

42
Q

in 2014 - how many children were overweight or obese?

A

41 million

43
Q

In relation to food - why is obesity rising?

A

There is a rising cost of healthy food as well as food scarcity in developing countries

44
Q

What are the top 3 ranked obese countries?

A
  1. Nauru (61% of population have BMI larger than 30)
  2. Cook islands (55.9% of the population)
  3. Palau (55.3% of the population)
45
Q

What do health programs target with targeting obesity?

A
  • Healthy diet
  • Physical exercise
  • Depression management
46
Q

What does an obesogenic environment look like?

A

Sedentary lifestyle, less manual labour, more car use, remote controls, mobile phones, more fast food and less cooking as well as more snacking

47
Q

What is the average weight loss from behavioural interventions after 12 months?

A

-2.8kg

48
Q

Which behavioural approaches for weight management were effective?

A

Calorie counting, contact with a dietician, and use of behaviour change techniques that compare participants’ behaviours with others were associated with greater weight loss

49
Q

What is the effectiveness of school‐based interventions for reducing children’s excessive weight gain?

A

Evidence suggests school‐based interventions that target enjoyable physical activity are generally effective in reducing excessive weight gain

However:
Need more research on Interventions that target broader behaviours such as diet and maintenance of weight reduction

50
Q

Effects of Mindfulness training on weight loss & health‐related behaviours in overweight & obese adults?

A

No significant effect on weight loss

But:
Short term effectiveness for reducing impulsive eating & binge eating as well as short term increases in physical activity

51
Q

Is relapse an issue with weight loss programs?

A

Yes it is a significant problem

52
Q

which psychosocial factors predict better maintenance & reduced relapse after intervention?

A
  • Higher levels of motivation
  • Self-efficacy for coping with barriers
  • Self-regulation skills
  • Positive body image
53
Q

Which certain elements of a built environment encourage physical activity?

A

Facility accessibility (e.g.,cycle paths, access to local parks)
Opportunities for being active (e.g.,home equipment, local area opportunities for physical activity)
Safety (e.g. local neighbourhoods safe from crime)
Aesthetics (e.g.,enjoyable scenery)

54
Q

What is the diabetes prevention program?

A

A comprehensive array of behavioural techniques
Individual case management by “lifestyle coaches” who also delivered the intervention.

10 years: Continued to have delay in development of diabetes by 34% compared with participants who took a placebo

15 years: Program continued to have a delay in development of diabetes by 27%

people who are at high risk for type 2 diabetes can prevent or delay disease by losing a modest amount of weight through lifestyle changes (dietary changes and increased physical activity).
Taking metformin, a safe and effective generic medicine to treat diabetes, was also found to prevent the disease, though to a lesser degree

55
Q

Look AHEAD (Action for Health in Diabetes) study

A

8 year weight losses achieved
Comprehensive behavioural weight loss counselling over the 8 years
Look AHEAD’s produced clinically meaningful weightloss (≥5%) of initial weight at year 8 in 50% of patients with type 2 diabetes
26.9% lost ≥10% of initial weight

May be used to manage other obesity‐related co‐morbid conditions
