Study Notes

Hypokinetic Diseases

Hypokinetic diseases are linked to a lack of physical activity or too little regular exercise.
Regular physical activity promotes good health, prevents diseases, and aids in disease treatment.
Inherited risks can be overcome with lifelong physical activity.

Obesity

Obesity is defined as having an excessively high amount of body fat relative to lean body mass (20% more than ideal body weight).
It's a chronic disease, not a cosmetic problem.
Obesity increases the risk of various health issues, including hypertension, type 2 diabetes, and heart disease.

Prevalence of Obesity (Youth & Adults)

Prevalence rates vary by sex and age for both youth (2-19 years) and adults (20 and over).
CDC/NCHS's National Health and Nutrition Examination Survey (2011-2014) provides data on prevalence rates.
Significant differences in prevalence often exist between different age groups and genders.

Definition of Obesity (BMI)

Body Mass Index (BMI) ≥ 30 indicates obesity.
BMI is a measure of body weight relative to height, based on the concept that weight should be proportional to height.

BMI Calculation

Formula: Weight (kg) / (Height (m) x Height (m))
or: Weight (kg) / (Height (cm) x Height (cm)) x 10,000

BMI Table

BMI Categories:
- Below 18.5: Underweight
- 18.5 - 24.9: Normal
- 25.0 - 29.9: Overweight
- 30 and above: Obese

Causes of Obesity

Genetics play a role.
Lifestyle choices are the primary factors. This includes food intake and caloric expenditure.
Knowledge of nutrition is important.
Stress levels can play a role.
Medications (such as antidepressants) can impact weight.
Environmental factors can influence eating habits, such as food availability and cultural norms.
Caloric balance (intake exceeding expenditure) leads to weight gain.
A positive caloric balance results when you consume more calories than you burn. Negative caloric balance happens when you consume less calories than you burn leading to weight loss.
- Resting Metabolic Rate (RMR) is the most significant contributor.

Daily Caloric Needs

RMR accounts for 60-70% of the daily caloric need.
Activity consumes 20-30% of daily caloric needs.
Thermic effect of food takes up the remaining 10%.

Resting Metabolic Rate (RMR)

RMR is the number of calories your body burns at rest to maintain basic functions.
RMR is typically 60-70% of daily caloric expenditure.
RMR is proportionally linked to body weight and often declines with age.
More calories are required to sustain muscle than fat.

Treatment of Obesity

Treatment involves long-term management requiring behavior modifications.
Modifications include changing eating habits, increasing physical activity, and maintaining behaviors.
Understand and manage psychological and social stressors.
In severe cases, stomach-reducing surgical procedures may be considered.

Activity Level and Risk of Obesity

Increased hours spent sitting and watching television correlate with a higher relative risk of obesity.

Changing Lifestyle to Promote Healthy Weight

Reduce total calories.
Reduce fat intake.
Increase physical activity.
Change unhealthy eating behaviors.
Maintain detailed records of eating habits.
Plan meals and snacks.
Seek support from others.
Establish a reward system to help maintain healthy habits.

Weight Loss Gimmicks and Gadgets

Some methods are marketed as quick fixes but don't actually lead to lasting weight loss.
Saunas and sweat suits can cause dehydration.
Electrical stimulators have not been clinically proven effective for weight loss.
Spot reduction (targeting specific areas) is a myth.

Body Image

Body image is the mental representation of one's body.
It includes perceptions, images, thoughts, feelings, attitudes, and emotions.
Media often promotes negative body images.
Different cultures have varying ideals of beauty.
Poor body image can contribute to psychological distress.
Coping mechanisms can be used to deal with stress due to eating.

Coping Strategies

Analyze eating habits to efficiently address any stress eating behaviors.
Develop healthy strategies to deal with stress, which may be related to eating habits.

Signs of Disordered Eating

Preoccupation with food, calories, and weight.
Repeated expression of concerns about being fat, even if weight is average or below average.
Increased self-criticism about body image.
Secretly eating or stealing food.
Eating large portions followed by trips to the bathroom.
Excessive eating not consistent with weight.
Bloodshot eyes after consuming meals.
Vomiting or the smell of vomit in a bathroom.
Wearing baggy or layered clothing.
Mood swings.
Preoccupation with the dieting behaviors of others.
Drinking large quantities of diet soda or water.
Periods of severe caloric restriction.
Excessive use of laxatives.
Compulsive exercise not part of a training regimen.
Unwillingness to eat in front of others.

Strategies for Weight Gain

Increase calorie intake by 200-1000 kcal per day.
Increase the number of snacks.
Prioritize nutritious foods (whole grains, fruits, vegetables).
Favor complex carbohydrates in the diet for weight gain.
Include resistance training in the daily routine to enhance lean mass.
Consuming 1.5g of protein per kilogram of body weight is recommended.
Add milk and fruit juices to the diet to provide extra calories and nutrients.

Health Consequences of Overweight and Obesity

Hypertension (high blood pressure).
Type 2 diabetes.
Increased risk of heart disease.
Increased risk of stroke.
Respiratory problems.
Increased risk of certain cancers (e.g., breast, colon). Reduces the body's performance in physical activities.
More than 400,000 premature deaths annually.
Weight loss can reduce the risk of certain diseases.

Diabetes

Diabetes is a disease where blood sugar (glucose) levels are chronically high, typically due to a lack of insulin production or a decrease in insulin use by the body.
Insulin is a hormone that regulates blood glucose levels.
Diabetes has different types (type 1, type 2, and gestational) each with unique causes and conditions.
Type 1 diabetes is usually an autoimmune disorder, and individuals need external insulin.
Type 2 diabetes is often linked to obesity and lifestyle, with resistance to insulin action.
Gestational diabetes develops during pregnancy and often subsides after childbirth.
Tests include an overnight-fasting blood sugar test (FPG) and an oral glucose tolerance test for proper diagnosis.

Symptoms of Diabetes

Frequent urination.
Increased thirst.
Unusual weight loss.
Weakness or fatigue.
Blurred vision.
Tingling or numbness in hands or feet.
Slow-healing cuts or sores.
Erectile dysfunction in males.
Unusual vaginal dryness in women.
Extreme hunger.
Unexplained nausea or vomiting.
Frequent infections and/or urinary tract infections.

Causes of Diabetes

Certain medications.
Pregnancy (gestational diabetes).
Illnesses or diseases that damage the pancreas.
Genetics play a role in diabetes.
Obesity.

Long-Term Diabetes Complications

Heart and blood vessel disease.
Stroke.
Kidney damage.
Eye damage (leading to blindness).
Foot damage (potential amputation).

Prevention of Obesity Through Physical Activity

Combining caloric restriction with aerobic exercise is most helpful for preventing and controlling obesity.
Exercise alone may not be sufficient to induce noticeable weight loss in many cases.

Exercise Prescription

For aerobic activity, do 150 minutes per week at least.
For optimal long-term weight control, do 200-300 minutes of aerobic activity per week.
Dedicate at least 3 days a week to 40 to 60 minutes of exercise.
Start with an intensity of 40 to 50% of VO2 max progressively increase to 50-70%.
Aim for exercise energy expenditure of 300 to 500 kcal per day.
Stay hydrated and avoid overheating during exercise.
Include resistance training for maintaining lean tissue.

Combining Caloric Restriction With Exercise

Appropriate weight loss targets 0.5 to 1 kg per week.
Avoid extremely low-calorie diets (fewer than 1200 kcal per day).
Eat balanced and nutritious diets rich in vitamins and minerals.
Lower fat intake from the diet.

High Blood Pressure (Hypertension)

High blood pressure is the force of blood against the walls of the arteries.
Blood pressure is measured in mmHg, expressed as systolic/diastolic pressures (e.g., 120/80).
Hypertension is usually defined as blood pressure above 140/90.
High blood pressure often goes unnoticed until it causes significant damage to organs over time, that's why it is called a silent killer.

What Causes High Blood Pressure?

Unknown in most cases.
Potential contributing factors include narrowing of the arteries, rapid heart rate, kidney disease, and specific medications.

Who Gets High Blood Pressure?

African Americans are more prone to high blood pressure than other groups.
Older individuals (35-50 years old).
People who are overweight or obese.
People with a family history of high blood pressure.
Smokers.

Controlling Your Blood Pressure

Lifestyle changes can help prevent and control high blood pressure.

Quit smoking.
Limit alcohol consumption.
Manage stress effectively.
Maintain a healthy diet that includes lower amounts of sodium and salt.
Achieve a healthy weight.
Exercise regularly.

Points to Remember (High blood pressure)

A healthy diet (rich in fruits, vegetables, and low-fat dairy products) is crucial.
Minimize sodium and salt intake in the diet.
Maintain a healthy weight.
Incorporate physical activity into a daily routine.

Heart Diseases

Any disorder that affects the heart is considered a heart disease.

Atherosclerosis

A condition where the arteries' walls become hardened and thickened because fatty deposits build up inside (plaque).
The narrowed arteries lead to decreased blood flow.
Atherosclerosis is considered a substantial risk factor for heart diseases.
Risk factors include high cholesterol, and high blood pressure.

Causes of Heart Diseases

Age
Hereditary
High blood pressure
Diabetes
Obesity
Inactivity
High blood cholesterol
Alcoholism
Smoking

Angina

Angina is chest pain or discomfort related to coronary heart disease.
Results from reduced blood flow to the heart muscle, leading to reduced oxygen supply.
Narrowing of coronary arteries restricts blood flow to parts of the heart, triggering the pain.

Angina Symptoms

Pressure, tightness, or fullness in the chest.
Squeezing or pain in the center of the chest.
Discomfort may extend to the neck, jaw, shoulder, back or arm.

When Angina Occurs

Typically when the heart requires an increased blood flow (such as during vigorous exercise, strong emotions, or extreme temperatures).
Can occur even while resting in cases of coronary artery spasms.

Heart Attacks

Heart attacks occur when the blood flow to the heart muscle is reduced or completely blocked due to a clot in the coronary arteries.
Cholesterol plaque accumulation in arteries and/or blood clots commonly contributes to this blockage.
Reduced blood flow can cause damage or death of heart muscle, depending upon the extent of the blockage and duration.

Heart Disease Symptoms

Chest tightness or discomfort.
Heaveiness, pressure, or squeezing sensation in the chest.
Shortness of breath.
Sweating or weakness.
Nausea or vomiting.
Denial of symptoms.
Dizziness, tiredness, headaches, and/or pain in the chest and left shoulder.

Prevention and Treatment of Heart Diseases

Lifestyle modifications are important to decrease the risk of heart problems.
Quitting smoking.
Managing cholesterol levels.
Lowering blood pressure.
Increasing physical activity.
Maintaining a healthy weight.
Avoiding excessive alcohol consumption.
Utilizing appropriate medications.
Incorporating aspirin or other medications as prescribed.

Osteoporosis

Osteoporosis characterized by low bone mass and structural bone weakness.
Increased risk of bone fractures (e.g., hip, spine, wrist).
Bone density decreases over time.
Age, ethnicity, and gender are factors that cannot be modified.

Risk Factors of Osteoporosis(that you can't control)

Genetic predisposition.
Ethnicity (Caucasian and Asian women most at risk).
Age (classic osteoporosis occurs in adulthood).
Gender (Women, and especially postmenopausal).
Body size (smaller, thinner individuals).

Risk Factors of Osteoporosis (you can change)

Lack of regular exercise.
Smoking.
Eating disorders (such as anorexia nervosa and bulimia).
Excessive alcohol intake.
Low calcium and vitamin D intake.
Excessive soda consumption.
Medications (certain drugs increase the risk of bone loss).

Pregnancy & Breastfeeding and Bone Health

During pregnancy and breastfeeding, women experience a decrease in bone density during this process (3-5 per cent loss is a typical number cited).
This can be due to the baby's increased need for calcium. Calcium is drawn from the mother's reserves.

Osteoporosis Symptoms

The disease progresses without showing overt symptoms (silent disease).
Pain and fractures are common signs of severe symptoms.
Bone deformation.
Joint issues near affected areas.
Nerves can be compressed by enlarged bones (loss of sensation or movement).
Chronic back pain.
Gradual height reduction.

Prevention & Treatment of Osteoporosis

Starting early in one's life to build strong bones should be prioritized (teens).
Maintain adequate calcium intake daily (1500mg/day for postmenopausal women).
Vitamin D intake is crucial, especially for older adults.
Quitting smoking and limiting alcohol consumption can help.
Understand and manage any known risk factors.
If necessary, consider hormone replacement therapy (HRT) to slow bone loss.
Consistent participation in regular exercise programs. This includes doing weight-bearing exercise.
