Nutrient intake and bone health status of Korean male college students as related to smoking situations

Abstract

The purpose of this study was to compare the dietary habits, nutrient intake, bone mineral density (BMD) and bone metabolism in Korean male collegians as related to smoking situation. One hundred sixty one young adult males at the age of 20-26 participated in this study. The subjects were divided into four groups: non smoker (n=42), light smoker (n=34), moderate smoker (n=49) and heavy smoker (n=36). The anthropometric characteristics, smoking situations, dietary habits and nutrient intakes were observed. Bone status of the calcaneus was measured by using quantitative ultrasound (QUS). Bone metabolism markers including serum alkaline phosphatase activity (ALP) and N-mid osteocalcin (OC) were analyzed. There were no significant differences in height, weight, BMI, energy and calcium intake among the four groups. Iron intake of moderate and heavy smoker was significantly lower than that of light smoker. Heavy smokers consumed significantly lower vitamin C than moderate smokers, and their coffee consumption and lifetime alcohol consumption were significantly highest among the 4 groups. QUS parameters and serum ALP were not significantly different among the four groups. Serum OC levels were significantly lower in heavy and non smoker group compared to the moderate smoker group. In conclusion, heavy smokers in young male collegians had undesirable lifestyle and dietary habits, like as high consumption of coffee and alcohol, and low intake of Fe and vitamin C. Although, there was no significant difference in their current bone status from the other groups, these undesirable factors with heavy smoking may affect their bone health in the long term.

Elevated Serum Iron Is a Potent Biomarker for Spirometric Resistance to Cigarette Smoke among Japanese Males: The Takahata Study

“…Another limitation of the present study was the lack of information on iron intake in the study population. Low intakes of iron have been reported among young smokers in Korea [24]. The difference in serum levels of iron between smoke resistant and non-resistant subjects may be attributable to differences in daily intake of iron from food.…”

Less Healthy Dietary Pattern is Associated with Smoking in Korean Men According to Nationally Representative Data

“…An imbalanced diet may be one of the reasons for the low health-related quality of life in smokers (24). Also, Korean male smokers consumed less calcium but more coffee and alcohol, which is obviously detrimental to their bone health (9). There is even a theory suggesting that caffeinated or alcoholic beverages may enhance the taste of smoking (10).…”

“…Previous Korean studies on the nutrient intake of smokers were only sporadically reported, and most subjects were too small or too focused on specific groups (9, 10). Therefore, further study on the nutrient intake and dietary pattern of smokers should broaden its approach to consider a nationally representative sample.…”

Systematic review/Meta-analysis Coffee consumption and risk of fractures: a meta-analysis

“…For example, milk intake (or calcium intake from any source), one of the most import confounding factors, was adjusted in only four included studies. Smoking is also known to be associated with coffee consumption [38], and evidence showed that of all hip fractures, one in eight was attributable to smoking [46]. But not all original data extracted have been adjusted for it.…”
