2. Jossy is a 6-year-old girl and is in elementary school. At her last doctor visit, her measured height was 46 inches and her weight was 61 pounds. Her pediatrician voiced concern over Jossy’s excessive weight gain over the past year. Her usual diet consists of sweetened cereal with whole milk and fruit juice for breakfast and a juice drink and crackers for her mid-morning snack. On school days, Jossy buys her lunch at school; her favorite menu items are pizza and tacos. Jossy’s mom states that she started a new job this past year, which requires that Jossy attend an after-school program until 6 in the evening. She receives a snack there, usually an 8 oz box of fruit juice and crackers. Jossy’s parents report that Jossy is “always hungry” and they will often stop for her favorite chicken nuggets, fries, and soda on late evenings when the family is too tired to cook. Jossy likes to play video games and has a computer and television in her room. Her father complains that she spends more time in her room than playing outside. Jossy’s mother is overweight and her father is of normal weight, although he states he was overweight when he was a child. The family has discussed getting more exercise on the weekends but are not sure how to add this to their already busy schedules.

   1. Calculate Jossy’s body mass index (BMI) and use this to evaluate her weight status using the information in How To 16-2 on page 514 in the text.

   2. From the information in chapter 16 in your text, what are some factors that may have contributed to Jossy’s excess weight gain over the past year?

   3. Considering her age and the information in chapter 16, what do you think would be a reasonable weight management goal for Jossy?

   4. Using the recommendations in Table 16-10, what strategies would you suggest that Jossy and her parents incorporate into their current lifestyle?

   5. Based on her usual intake, identify at least 2 or 3 nutrients likely to be deficient in Jossy’s diet. What major food groups provide these nutrients?

   6. Assuming her current level of activity, what are Jossy’s estimated daily kcalorie needs according to Table 16-7?

3. Chablis is a 14-year-old female who has been referred to you by her mother and family physician. Chablis’ mom is concerned that she is not eating right and her doctor wants you to give Chablis some nutrition advice because she wants to be a vegetarian. Chablis has heard that red meat contains a lot of fat and she “does not want to get fat.” A physical exam by her physician shows that Chablis is in the early stage of sexual maturation, she weighs 89 pounds, and she is 5 feet tall. Chablis is extremely active, spending every afternoon after school playing some kind of sport – basketball, swimming, track, or soccer.

   1. List at least four questions you would include in your assessment session with Chablis. Why would you include these questions?

   2. How would you address Chablis’ concern about meat and her desire to be a vegetarian? What are some sources of valid nutrition information you might recommend?

   3. How would you counsel Chablis regarding her desire not to get fat?

   4. As a healthcare professional, what advice would you give Chablis’ parents regarding their interactions related to food?

4. Compare the nutrient needs on the basis of per pound body weight for a 5-month male infant (13 pounds) and the 20-year-old male adult (160 pounds) for kcalories, protein, vitamin D, vitamin C, calcium, and iron – complete the following chart.

   NOTE: To calculate the per pound amount, divide the nutrient need by the number of pounds of the individual.

   Per Pound Nutrient 5 month old male infant 20 year old male kcalories Protein, g Vitamin D, µg Vitamin C, mg Calcium, mg Iron, mg What conclusions can you draw from the information you have recorded?

5. Desi L. has been breastfeeding her baby since he was born seven months ago. When she and her husband took the baby to the pediatrician for his check-up, they were told that he was anemic. They were surprised, since they thought that human milk contained all of the nutrients the baby needed for the first year of life. How can you explain the baby’s anemia?

The study of nutrition throughout different life stages is critical to understand the specific dietary needs that evolve from infancy through adolescence. Each stage presents unique challenges and requirements for adequate nutrient intake to support growth and development. In this paper, we will discuss various aspects of life cycle nutrition as they pertain to specific cases, utilizing scientific research and data from the DRI tables.

Life Cycle Nutritional Definitions

Adolescence refers to a developmental period that generally spans the ages of 10 to 19 years where individuals undergo significant physical, emotional, and social changes. Adverse reactions are negative health responses resulting from food consumption, such as allergies or intolerances. Alpha-lactalbumin is a protein found in whey that is predominant in human breast milk and is crucial for infant growth. Anaphylactic shock is a severe, potentially life-threatening allergic reaction requiring immediate medical attention. Botulism, caused by Clostridium botulinum, can be a severe foodborne illness; breast milk banks are facilities that safely collect, screen, process, and store donated human milk. Colostrum is the first milk produced after giving birth, rich in antibodies. Complementary foods are those introduced alongside breast milk/formula around six months of age. Food allergies involve immune responses to specific proteins, while food intolerances are non-immune related reactions. Gatekeepers refer to individuals responsible for food choices within households. Hyperactivity describes a condition often observed in children characterized by excessive movement and impulsivity. Lactoferrin is a protein in milk that aids iron absorption. Milk anemia is a condition resulting from iron deficiency often seen in infants consuming excessive amounts of cow's milk. Nursing bottle tooth decay is a decay pattern in infants due to prolonged exposure to sugary liquids. Puberty indicates the bodily changes adolescents undergo towards sexual maturity. Tolerance level refers to the amount of a substance that can be consumed without adverse effects. Weaning is the gradual transition from breastfeeding to solid foods.

Analysis of Jossy's Nutritional Status

To evaluate Jossy's weight status, we first calculate her BMI using the formula:

BMI = weight (lbs) / (height (in) x height (in)) x 703.

Jossy's BMI is calculated as follows:

BMI = 61 / (46 x 46) x 703 = 30.5, placing her in the overweight category according to the CDC guidelines.

Several factors contribute to Jossy’s weight gain, including the high-calorie density of her diet, lack of regular physical activity, and potential emotional eating in response to lifestyle changes at home.

A reasonable weight management goal for Jossy would be to stabilize her weight while increasing her physical activity, aiming for a gradual transition to a healthier lifestyle. Recommendations should involve incorporating family activities, such as weekend hikes and cooking nutritious meals together.

Deficiencies likely in Jossy's diet may include iron, fiber, and vitamin D, primarily obtained from fruits, vegetables, and whole grains, which are underrepresented in her current meals.

Based on her physical activity level and guidelines outlined in her textbook, Jossy's daily calorie needs are estimated at approximately 1,600 to 1,800 kcal.

Nutrition Counseling for Chablis

In assessing Chablis’s situation, I would include questions about her daily food intake, knowledge of vegetarian diets, reasons for wanting to be a vegetarian, and her physical activity levels. These aspects help tailor the guidance effectively. Addressing her concerns regarding meat, it is essential to inform her that a well-planned vegetarian diet can be nutritious, and alternative protein sources include legumes, nuts, and soy products.

To ensure Chablis does not experience weight gain, counseling should emphasize balanced nutrient intake while maintaining physical activity. Encouragement for healthy food choices without labeling foods as 'bad' will foster a positive relationship with food.

Advising her parents should focus on establishing supportive eating habits and positive reinforcement, including cooking together and encouraging physical activities without competing or judgment.

Nutrient Needs Comparison

When comparing nutrient needs between infants and young adults, it’s evident that infants require a higher proportional intake of calories and protein due to rapid growth. For instance, the requirement for protein may be higher per pound in infants, necessitating focused dietary strategies and timing as their diets transition.

Addressing Anemia in Infants

Infant anemia, even when breastfeeding, often results from insufficient iron intake, especially around six months when iron stores deplete. Exclusively breastfeeding infants may require iron supplementation or introducing iron-fortified foods to meet their growing needs (Joyce, C. & Hue, P., 2019).

Conclusion

Understanding life cycle nutrition is crucial for promoting health and well-being at all stages of life. By exploring the nuanced dietary requirements of children and adolescents, we can develop effective strategies to support their growth and nutritional needs.
