This study was performed to investigate the association between hair mineral levels and nutrient intakes, age, and BMI in female adults who visited a woman's clinic located in Seoul. Dietary intakes were assessed by food frequency questionnaire and mineral levels were measured in collected hairs, and the relationship between these was examined. The average daily nutrient intakes of subjects were compared to those of the KDRIs, and the energy intake status was fair. The average intake of calcium in women of 50 years and over was 91.35% of KDRIs and the potassium intake was greatly below the recommended levels in all age groups. In the average hair mineral contents in subjects, calcium and copper exceeded far more than the reference range while selenium was very low with 85.19% of subjects being lower than the reference value. In addition, the concentrations of sodium, potassium, iron, and manganese in the hair were below the reference ranges in over 15% of subjects. The concentrations of sodium, chromium, sulfur, and cadmium in the hair showed positive correlations (P < 0.05) with age, but the hair zinc level showed a negative correlation (P < 0.05) with age. The concentrations of sodium, potassium, chromium, and cadmium in the hair showed positive correlations (P < 0.05) with BMI. Some mineral levels in subjects of this study showed significant correlations with nutrient intakes, but it seems that the hair mineral content is not directly influenced by each mineral intake. As described above, some hair mineral levels in female adults deviated from the normal range, and it is considered that nutritional intervention to control the imbalance of mineral nutrition is required. Also, as some correlations were shown between hair mineral levels and age, BMI, and nutrient intakes, the possibility of utilizing hair mineral analysis for specific purposes in the future is suggested.
本研究旨在调查首尔某女性诊所就诊的成年女性的头发矿物质水平与营养素摄入量、年龄和 BMI 的相关性。通过食物频率问卷评估膳食摄入量，通过收集的头发测量矿物质水平，并检查它们之间的关系。将受试者的平均每日营养素摄入量与 KDRIs 进行比较，能量摄入状态良好。50 岁及以上女性的钙平均摄入量为 KDRIs 的 91.35%，所有年龄段的钾摄入量均大大低于推荐水平。在受试者的平均头发矿物质含量中，钙和铜远远超过参考范围，而硒的含量非常低，85.19%的受试者低于参考值。此外，头发中钠、钾、铁和锰的浓度在超过 15%的受试者中低于参考范围。头发中钠、铬、硫和镉的浓度与年龄呈正相关（P<0.05），但头发锌水平与年龄呈负相关（P<0.05）。头发中钠、钾、铬和镉的浓度与 BMI 呈正相关（P<0.05）。本研究受试者的一些矿物质水平与营养素摄入量呈显著相关，但头发矿物质含量似乎不受每种矿物质摄入量的直接影响。如上所述，一些成年女性的头发矿物质水平偏离正常范围，需要进行营养干预以控制矿物质营养失衡。此外，由于头发矿物质水平与年龄、BMI 和营养素摄入量之间存在一些相关性，因此未来可能有必要利用头发矿物质分析来达到特定目的。
