  1. Childcare improves handgrip strength in humans (OR = 0.26).

    “Grandparents who provided care for more than half the year were also less likely to have lower handgrip strength than those who provided less frequent care (OR = 0.26).”

    “grandparents who provided childcare for an average of less than 40 h per week (Odds Ratio [OR] = 3.62) were more likely to have lower handgrip strength”
