正如世界卫生组织所言“健康的生活方式，如坚持合理膳食、适量运动等是个人拥有健康之心身的基石。”因此，人们必须从小养成一个较好的生活习惯，以遵循健康的生活方式。那么如何才能够让咱们的孩子从小养成一个良好的生活习惯呢？显然，父母之示范和/或教导最为重要！这不，来自美国俄勒冈州立大学的研究正好支持本人的上述观点，即２～４岁之年龄段的孩子们觉醒状态下是“喜欢去户外玩耍，还是成天呆在沙发上玩手机或看电视、吃爆米花，其主要决定要素是父母的生活习惯。”

Parents Key to Whether Kids Get Enough Exercise, Studies Find

When grownups aren't around, children spend less time being active

THURSDAY, July 5 (HealthDay News) -- Parents play a major role in whether their young children are active or become "couch potatoes," according to two new studies.

In one study, Oregon State University researchers looked at 200 families with children ages 2 to 4 to determine how parenting style affects children's physical-activity levels.

All the children spent four to five hours sitting during a typical day, but children of parents deemed "neglectful" (those who weren't home often and spent less time with their children) spent up to 30 additional minutes a day watching television, playing video games or being engaged in some other type of screen time.

"A half an hour each day may not seem like much, but add that up over a week, then a month, then a year and you have a big impact," study lead author David Schary, a doctoral student in the College of Public Health and Human Sciences, said in a university news release. "One child may be getting up to four hours more active play every week, and this sets the stage for the rest of their life."

Schary was even more alarmed to find that all the children were sitting for several hours a day.

"Across all parenting styles, we saw anywhere from four to five hours a day of sedentary activity," Schary said. "This is waking hours, not including naps or feeding. Some parents counted quiet play -- sitting and coloring, working on a puzzle -- as a positive activity, but this is an age where movement is essential."

In the second study, Schary and a colleague looked at the same families and found that active play was most common among children whose parents played with them. But any level of parental encouragement -- even just watching their child play or driving them to an activity -- had a positive effect.

"When children are very young, playing is the main thing they do during waking hours, so parental support and encouragement is crucial," Schary said. "So when we see preschool children not going outside much and sitting while playing with a cell phone or watching TV, we need to help parents counteract that behavior."

The studies were published June 21 in the journal Early Child Development and Care.
