Not all infant formulas are alike: Differential effects on weight gain

Not All Infant Formulas Are Alike: Differential Effects on Weight Gain


ScienceDaily (Dec. 28, 2010) — New findings from the Monell Center reveal that weight gain of formula-fed infants is influenced by the type of formula the infant is consuming. The findings have implications related to the infant's risk for the development of obesity, diabetes and other diseases later in life.

"Events early in life have long-term consequences on health and one of the most significant influences is early growth rate," said study lead author Julie Mennella, Ph.D., a developmental psychobiologist at Monell. "We already know that formula-fed babies gain more weight than breast-fed babies. But we didn't know whether this was true for all types of formula."
While most infant formulas are cow's milk-based, other choices include soy-based and protein hydrolysate-based formulas. Protein hydrolysate formulas contain pre-digested proteins and typically are fed to infants who cannot tolerate the intact proteins in other formulas.
In adults, pre-digested proteins are believed to act in the intestine to initiate the end of a meal, thus leading to smaller meals and intake of fewer calories. Based on this, the authors hypothesized that infants who were feeding protein hydrolysate formulas would eat less and have an altered growth pattern relative to infants feeding cow's milk-based formula.
In the study, published online in the journal Pediatrics, infants whose parents had already decided to bottle-feed were randomly assigned at two weeks of age to feed either a cow's milk-based formula (35 infants) or a protein hydrolysate formula (24 infants) for seven months.
Both formulas contained the same amount of calories, but the hydrolysate formula had more protein, including greater amounts of small peptides and free amino acids.
Infants were weighed once each month in the laboratory, where they also were videotaped consuming a meal of the assigned formula. The meal continued until the infant signaled that s/he was full.
Over the seven months of the study, the protein hydrolysate infants gained weight at a slower rate than infants fed cow milk formula. Linear growth, or length, did not differ between the two groups, demonstrating that the differences in growth were specifically attributable to weight.
"All formulas are not alike," said Mennella. "These two formulas have the same amount of calories, but differ considerably in terms of how they influence infant growth."
When the data were compared to national norms for breast-fed infants, the rate of weight gain of protein hydrolysate infants was comparable to the breast milk standards; in contrast, infants fed cow's milk formula gained weight at a greater rate than the same breast milk standards.
Analysis of the laboratory meal revealed the infants fed the protein hydrolysate formula consumed less formula during the meal.
"One of the reasons the protein hydrolysate infants had similar growth patterns to breast-fed infants, who are the gold standard, is that they consumed less formula during a feed as compared to infants fed cow's milk formula" said Mennella. "The next question to ask is: Why do infants on cow's milk formula overfeed?"
The findings highlight the need to understand the long-term influences of infant formula composition on feeding behavior, growth, and metabolic health. Future studies will utilize measures of energy metabolism and expenditure to examine how the individual formulas influence growth, and how each differs from breastfeeding.
Also contributing to the study, which was funded by the National Institute of Child Health and Human Development, were Monell scientists Gary Beauchamp and Alison Ventura.

Treating women’s depression might help them lose weight

Treating Women’s Depression Might Help Them Lose Weight


ScienceDaily (Dec. 27, 2010) — For many women coping with obesity and depression, new research finds that improving your mood might be the link to losing weight.

The new study, which appears in the November/December issue of the journal General Hospital Psychiatry, cites past surveys that show having a body mass index (BMI) of 30 or more — classified as obese — increases a person’s risk of depression by 50 percent to 150 percent.
“I expect that the relationship between depression and physical activity goes in both directions,” said lead author Gregory Simon, M.D., of Group Health Research Institute in Seattle. “Increased physical activity leads to improvement in depression and improvement in depression leads to increased physical activity. We see in our study that they go together, but we can’t say which causes which.”
Simon and his colleagues evaluated 203 women ages 40 to 65 with an average BMI of 38.3. Participants underwent baseline tests to measure their weight, depression score, physical activity and food intake.
They placed the women into two treatment groups — one focused on weight loss and the other focused on both weight loss and depression. Both interventions included up to 26 group sessions over 12 months, and researchers followed up on participants at six, 12 and 24 months after enrollment.
The researchers found the most significant changes happened in the first six months and then remained stable afterwards. At six months, among the women who had at least a one-half point decrease on the Hopkins Symptom Checklist depression score, 38 percent lost at least 5 percent of their body weight. This compared with 21 percent of the women who lost the same amount but had no decrease — or an increase — in their depression score.
“Most weight loss programs do not pay enough attention to screening and treatment of depression,” said Babak Roshanaei-Moghaddam, M.D., of the psychiatry and behavioral sciences department at the University of Washington in Seattle. “This study further underscores the importance of screening for depression in such programs that can potentially lead to both physical and psychological well-being.”

Study probes obesity link to fibromyalgia

Study Probes Obesity Link to Fibromyalgia


ScienceDaily (Jan. 1, 2011) — Afflicting up to 5 percent of the U.S. population, mostly women, fibromyalgia is characterized by widespread pain and range of function problems. A new study in The Journal of Pain reports there is close association between obesity and disability in fibromyalgia patients.

The purpose of the study, conducted by University of Utah researchers, was to evaluate the relationship between fibromyalgia and obesity. They hypothesized that obesity significantly adds to the disease and disability burden of the condition. Two hundred fifteen fibromyalgia patients were evaluated in the study and given several physical tests to measure strength, flexibility, range of motion, and strength. Heart rates and sleep quality also were assessed.
The authors reported that consistent with previous studies, obesity is common among those with fibromyalgia. Half the study sample was obese and an additional thirty percent were overweight. Also consistent with previous findings, obese patients in this study showed increased pain sensitivity, which was more pronounced in lower body areas. The obese patients also had impaired flexibility in the lower body and reduced strength.
The study concluded that obesity is a common comorbidity of fibromyalgia that may compromise clinical outcomes. The adverse impact of obesity is evidenced by hyperalgesia, disability, impaired quality of life and sleep problems. The authors also noted that recent evidence suggests weight loss improves fibromyalgia symptoms, perhaps resulting from patients adopting healthier lifestyles and taking more positive attitudes toward symptom management, and overall quality of life.
