-Genetics relates to the combinations of genes that an individual receives from their parents, and are what determines every physical feature of an individual.

-Genetics can influence the timing of the release of hormones and larger levels of testosterone at a young age can lead to rapid development of muscle mass and increased sex drive, positively impacting physical development.

-Faulty genes can result in adults developing Alzheimer’s disease, which can cause long-term memory loss and confusion, negatively affecting intellectual development.

-Individuals can be born with genetic predispositions to diseases such as Type 2 diabetes. Type 2 diabetes can cause long term damage to organs such as the kidneys, eyes and heart, which negatively affects intellectual development.

-Faulty genes can result in adults developing Alzheimer’s disease, which can cause long-term memory loss and confusion, negatively affecting intellectual development.

Body Weight

-Body weight is how much an individual weighs, and can be measured in kg and BMI. Also may refer directly to an individual’s fat levels.

-Low body weight can cause decreases in the rate of muscle development, negatively affecting physical development.

-High body weight can cause numerous health problems which may result in time spent in hospital, which can decrease learning opportunities at school and negatively impact intellectual development.

-Overweightness and obesity can result in low self-esteem, which can cause anxiety and depression, negatively impacting mental health.

-High body weight can cause numerous health issues such as high blood pressure and diabetes, both of which cause physical health to suffer.

Blood Pressure

-Blood pressure is the force of blood on the walls of the arteries. Can be measured systolically or diastollically.

-High blood pressure may result in individuals not being able to participate in physical activity which can result in a decrease in gross motor skills.

-High blood pressure also increase the risk of strokes. Strokes can result in losing certain abilities such as long-term memory and language skills, which negatively impacts intellectual development.

-High blood pressure increases the risk of strokes and cardiovascular disease, both of which negatively impact physical health.

-High blood pressure (hypertension) can cause failure of organs such as kidneys and heart, which negatively affects physical health.

Blood Cholesterol

-Refers to the levels of high density lipoproteins and low density lipoproteins in the blood, known collectively as cholesterol.

-High levels of high density lipoproteins positively affect the body’s physical development, because they help unclog arteries by removing excess LDLs, allowing individuals to participate in physical activity to improve their fitness and motor skills.

-Blood cholesterol in excess levels can cause strokes or heart attacks, which can result in time spent in hospital. This can negatively affect social development as the individual will have less chances to interact and communicate with friends and family.

-Individuals with excess blood cholesterol may decide to make better food choices such such as less fatty and oily foods, which will benefit their overall physical health.

-High amounts of HDLs and low amounts of LDLs are the ideal cholesterol levels for optimum health. An individual with these levels will experience positive effects on his/her physical health, such as a decreased risk of heart disease.

-The practice of inhaling tobacco through the burning of cigarettes. Has many negative side effects on physical health, such as increased risk of cancers and respiratory conditions.

-Tobacco smoking can cause respiratory conditions such as bronchitis that can affect how much oxygen is taken in by the body. This can negatively affect physical development because the individual may tire easily, decreasing their rate of muscle development.

-Tobacco smoking can cause many types of cancers, which can result in time spent in hospital. The stress of cancer therapy, possibility of death as well as isolation from family can cause huge levels of stress, which can impact how someone identifies and manages their emotions. This negatively impacts their emotional development.

-Tobacco smoking causes many types of cancers such as breast, lung, brain, stomach and prostate, which impacts physical health.

-People who smoke may be avoided by non-smokers, especially in public areas, preventing them from meeting new people, and their social health will be impacted.

Development
 Social: Housing stress causes an adult to face constant stress of paying bills and mortgage.  This negatively affects an adult’s social development because they aren’t in the same socioeconomic group because of the financial burden of the payments on their home.

Physical: constant stress on an adult’s finances that a home carries with it, this can negatively affect an adult’s physical health because stress can cause issues such as migraine/tension headaches, shoulder/neck pain, skin conditions, heartburn even diarrhoea or constipation.

Development: Using drugs, such as cannabis, can impact on physical development by resulting acute effects including the impairment of motor skills, reaction time and the ability to perform skilled activities. Drug use can also cause decreasing memory and learning abilities, impacting on an individual’s intellectual development.

Health: Mental health can be affected, as cannabis causes changes in the user’s moods, affects how they think and perceive the environment, and causes decreased motivation in areas such as study, work or concentration. The use of drugs can also impact on physical health by damaging body organs such as liver, brain, lungs, throat and stomach.
