Pregnancy Case Study: Meghan

Background

Today you are meeting with Meghan, a 39 year old non-Hispanic, White woman who is 20 weeks pregnant.  Meghan has been referred to you, a Registered Dietitian, by her obstetrician.  This is Meghan's first pregnancy.  Meghan is regional sales manager for an upscale clothing store that is having some economic difficulties right now; her company is in the middle of closing some stores and "downsizing."  Meghan shares with you that this was an unexpected pregnancy.  Meghan had always wanted to be a mother, but she was very busy building her career and never felt like it was the right time to "settle down."  Now she states that she is excited about her pregnancy, and has already been buying baby clothes and redecorating the second bedroom in her condo. Meghan attended a preconception health education class and will start a prepared childbirth class next month.  Meghan is an only child.  Meghan's mother and her mother's new husband live in New York, and as a newly retired couple, plan to travel a lot and spend their winters in Mexico.

Meghan had been dating the father of the baby, Peter,  for about six months when she discovered that she was pregnant.  Peter is 50 years old, an executive at Microsoft, and has two children ages 22 and 24.  Peter was initially reluctant to have another child, but being a mother was very important to Meghan, and Peter agreed to support her during this pregnancy. The work team that Peter leads is currently in the middle of a big push for the roll out of a new version of their software product.

Meghan is uncertain about breastfeeding at this point.  She plans to go back to work a month after she delivers, and is concerned that it would be too difficult to combine her work load with breastfeeding.

Fitness is important to Meghan.  She was a competitive runner in high school and college.  Meghan and Peter are part of a group of friends who socialize together during strenuous adult bike and ski trips.  Meghan continues to run about 15 miles a week - having cut back from about 30 miles per week before she was pregnant, due to increased fatigue. She has a membership in a health club, and typically uses the weights and the Stairmaster "2 or 3 times" per week.  She ways that In the last month she has added a water aerobics class to her routine to compensate for the reduction in her running.

There is a strong family history of obesity in Meghan's family; her father died at age 55 of heart disease that was probably related to the diabetes he developed in his 40s.  Meghan tells you that she worries about having a big baby who will be at high risk for these conditions as an adult.  Meghan also tells you that she has had to "work" to keep her weight under control, and she has found that a low carbohydrate diet is the most effective approach for her.  She tells you that once, when she failed to follow this diet for a few weeks her weight "ballooned" to 125 pounds.

Anthropometric Data

Meghan's prepregnancy weight was 120 pounds.   She is 69 inches tall.  Today her weight is 126 pounds.

Health History

Meghan's health history is unremarkable. Her blood pressure today is within normal limits. She denies use of drugs or tobacco.

With this pregnancy she continues to experience, fatigue, nausea, intermittent constipation and heartburn.

Laboratory Values

Last week Meghan had a 50 gram oral glucose screen. Results at one hour were 120 mg/100 ml. Meghan's  hematocrit today is 29%.

Supplements

Meghan tells you that she is taking fish oil capsules  to reduce her risk of developing hypertension and calcium to prevent leg cramps.  She tried standard prenatal vitamins but they seemed to increase her nausea.

Dietary Intake

Before the visit you asked Meghan to keep three day food records. She brings them with her today. She states that this pattern is typical.  Because she spends many days on the road visiting stores, she makes a point of taking her lunch and snack with her in a cooler so that she won't have to buy food of unknown quality on the road.   Weekends are variable depending on her social schedule, but she tries to get together with a group of friends every Sunday morning.  Meghan states that she works hard to avoid foods with fat and sugar. She will occasionally have one glass of wine or beer at social events.  In addition to the foods and beverages listed below, Meghan tells you that she usually carries a water bottle around with her and she makes a point of drinking at least 2 liters of water a day - more if it is hot or she has been exercising.

Questions:

  2. Assess Meghan's current nutritional status in terms of anthropometric data, health history, lab values, and dietary intake information.  Use both a nutrient analysis (http://www.nat.uiuc.edu/mainnat.html) and Food Guidance System (http://www.mypyramid.gov/mypyramidmoms/pyramidmoms_plan.aspx) approach to dietary analysis.
  3. What are the nutritional concerns you have about Meghan?  How might you prioritize these concerns in terms of addressing them in the limited time you have with Meghan today?
  4. What specific recommendations might you make regarding weight gain, diet, exercise, dietary supplements, and discomforts of pregnancy?
  5. You see Meghan again at her 32 week visit and she now weighs 140 pounds and her hematocrit is 31%.  What would you like to address at this visit?
