Bone density changes over time, peaking in the midthirties but decreasing much more rapidly once menopause has been reached (Condon, 2004). Lower bone density can lead to osteoporosis as well as result in more fragile and breakable bones. Other risk factors identified for decreased bone density include cigarette use, inadequate physical activity, and insufficient vitamin D intake or lack of sufficient exposure to natural sunlight (van Dijk, Kavousi, Troup, & Franco, 2015). In addition to the skeletal system, the cardiovascular system and integumentary system (skin and hair) also change during this time.
