Exercise as Treatment for Perinatal Mood Issues

 Here is an excellent REPRINT on exercise written by Kathleen Kendall-Tackett. Hats off to Kathleen for graciously offering this chapter to readers of WellPostpartum Weblog.

as effective as medications with far fewer

A growing body of research indicates that exercise is an effective treatment for depression, with efficacy comparable to that of medications.Traditionally, exercise has been recommended for people with mild-to-moderate depression. But as two clinical trials from Duke University Medical Center have found, exercise can also alleviate major depression as effectively as medications.
Exercise can also be safely combined with other modalities.

Exercise for Depressed People

Severalrecent studies have demonstrated that exercise improves mood. Many of these studies are of older adults, who are sometimes at higher risk for depression. For example, in a large population study from Finland (N=3,403), exercise lowered depression, and helped with feelings of anger, distrust and stress. Two to three times a week was enough to achieve this mood-altering effect (Hassmen et al. 2000). In another study, older adults were randomly assigned to either exercise classes or health education for 10 weeks (Mather et al., 2002). All participants were depressed and on medications, but medications were not adequately controlling their depression. At the end of treatment, 55% of the exercise group was less depressed vs. 33% of the education group.

Most of the participants in the previously cited studies had mild-to-moderate depression. But Babyak et al.’s (2000) study demonstrated that exercise can be helpful for major depression as well. In this clinical trial, depressed older adults were randomly assigned to one of three groups: exercise alone; sertraline alone; or a combination of exercise and sertraline. After four months, all the patients improved, and there were no differences between the groups. People in the exercise-only group did as well as people in the two medication groups. In addition, people in the exercise-only group were significantly less likely to relapse. Six months after completion of treatment, 28% of the exercise-only group became depressed again vs. 51% of the medications-only and medications-exercise groups. This same group of researchers recently replicated their findings (Blumenthal et al., 2007).
In the more recent study, 202 adults with major depression were randomized to one of four conditions: sertraline, exercise
at home, supervised exercise, or a placebo control. After four months of treatment, 41% of the patients were in remission and no longer met the criteria for major depression. Efficacy rates by treatment were as follows: supervised exercise=45%, home-based exercise=40%, medication=47%, and placebo=31%. The exercise condition was 45 minutes of walking on a treadmill at 70% to 85% maximum heart rate capacity, three times a week, for 16 weeks. The efficacy of exercise was comparable to medications for major depression.

Exercise to Achieve an Antidepressant Effect For mild to moderate depression
• Frequency: 2 to 3 times a week
• Intensity: moderate

• Duration: 20 to 30 minutes

For major depression

• Frequency: 3 to 5 times a week
• Intensity: 60% to 85% maximum capacity
• Duration: 45 to 60 minutes
Exercise and Breastfeeding

So exercise is good for treating depression, but will it negatively impact breastfeeding? Only a few studies have specifically
addressed this topic. A recent Cochrane Review found that neither diet nor exercise for weight loss appeared to impact breast feeding adversely (Amorin, Linne, & Lourenco, 2007). However, the authors noted that there was very little research on this topic.

An Australian study (Su et al., 2007) examined the relationship between 587 mothers’ exercise, initiation and duration of breast feeding, and exercise’s effect on infant growth. At 6 to 12 months, exercise had not decreased breastfeeding duration. At 12 months, exercise had no significant impact on infant growth. This applied to both women who were fully breastfeeding and those who did “any” amount of breastfeeding. The researchers concluded that their study should reassure health care providers that exercise while breastfeeding is safe and important for maintaining health. Those studies demonstrate that exercise is generally safe for breastfeeding mothers, but does exercise cause lactic acid to build up in mothers’ milk so that babies won’t breastfeed?
A study of 12 lactating women sought to answer this question (Quinn & Carey, 1999). Quinn and Carey found that in women with an adequate maternal caloric intake, moderate exercise did not increase lactic acid in breastmilk nor cause babies to reject it. When women exercised in the “hard” range (using the perceived-exertion scale), lactic acid increased. The authors recommended exercise in a moderate range because it neither increases lactic acid accumulation in breastmilk
nor alters babies’ willingness to breastfeed.

Summary
In summary, exercise is a highly effective treatment for depression-alone or in combination with other treatments. It
appears to have no negative effect on breastfeeding. It can be a viable alternative treatment if mothers refuse medications.

Now Available

Pregnant and postpartum women are at increased
risk for depression, and the health effects of
depression for both mother and baby are too serious
to ignore. As important as it is, however, to promptly
treat depression, some are voicing concern over
whether the risks of antidepressant medications
outweigh the benefits. In this monograph, Kathleen
Kendall-Tackett describes the various non-drug
treatment modalities being used to treat even major
depression. In most cases, the non-drug
treatments are as effective as
medications with far
fewer side effects. $18.95
