چکیده
این مقاله یک شبکه عصبی مصنوعی (ANN) را برای شناسایی زنان یائسه ارائه می‌کند که در معرض خطر بالای ابتلا به استئوپاتی هستند. در حالی که 800 بیمار در این مطالعه شرکت کردند، 180 بیمار برای آموزش شبکه مورد استفاده قرار گرفتند. از پارامترهای زیر استفاده شد: امتیاز T (از 2.5- تا 4-)، سن، سطح کلسیم خون (<1.9 mmol/L)، سطح ویتامین D خون (<20ng/ml)، شکستگی هیپ، شکستگی ستون فقرات، شکستگی مفصل، مصرف گلوکوکورتیکوئیدها، وضعیت سیگار کشیدن و BMI. شبکه دارای 10 پارامتر ورودی و 1 پارامتر خروجی است. برای معماری نهایی سیستم خبره، یک شبکه عصبی با 20 نورون در لایه پنهان بر اساس نتایج آموزش انتخاب شد. سیگنال هر نورون از لایه پنهان به نورون در لایه خروجی هدایت می شود، جایی که این نورون سیگنال را پردازش می کند و خروجی مورد نظر شبکه را می دهد. حساسیت 97.5٪، ویژگی 70٪، و دقت 94.44٪ بود.

Abstract
This paper presents an Artificial Nerual Network (ANN) for identification of postmenopausal women who are at high risk for developing osteopathy. While 800 patients took part in the study, 180 were used for network training. The following parameters were used: T-score (from −2,5 to −4), Age, Blood calcium level (<1,9 mmol/L), Blood vitamin D level (<20 ng/ml), Hip fracture, Spine fracture, Joint fracture, Glucocorticoids use, Smoking status, and BMI. The network has 10 input parameters and 1 output parameter. For the final architecture of expert system, a neural network with 20 neurons in hidden layer was chosen based on the training results. The signal from each neuron from hidden layer is directed to neuron in output layer, where this neuron processes the signal and gives desired output of the network. The sensitivity was 97,5%, specificity 70%, and accuracy 94,44%.
Introduction
Osteoporosis is a skeletal illness that causes weakening of the bones, which can lead to increased fractures. People with osteoporosis have decreased bone mass and microarchitectural degeneration of bone tissue, in addition to lower bone strength [1-3].
Osteoporosis is a skeletal illness that causes weakening of the bones, which can lead to increased fractures. People with osteoporosis have decreased bone mass and microarchitectural degeneration of bone tissue, in addition to lower bone strength [1-3].
According to data from 2010, 6,6% of men and 22,1% of women over 50 in the EU have osteoporosis. Because of the expanding number of patients worldwide, it is now referred to as a "silent epidemic." Variable and non-variable factors that raise the chance of developing osteoporosis and bone fractures can be separated. One of the most important variables is smoking, which is linked to decreased bone resistance to mechanical stresses and friction. The effects of excessive alcohol use on bone homeostasis are significant. Caffeine, glucocorticoid therapy, insufficient calcium and vitamin D intake, insufficient physical activity, low BMI, past bone fractures, and a family history of osteoporosis are all risk factors [4-6].
Conclusion
As osteoporosis in postmenopausal women is a rising problem in the modern world, predictive modelling of the risk of developing osteoprosis is highly desirable. This paper presents the development and validation of an ANN based model for prediction and automated diagnosis of osteoporosis in post-menopausal women based on risk-contributing factors. Giving the high accuracy and sensitivity of proposed ANN for identification of high risk of osteoporosis development in postmenopausal women, it can be concluded that AI has a high potential for decission making for this specific purpose. Prediction of high risk for osteoprosis development can contribute to adjustments in lifestyle and possible prevention of osteoporosis. In addition to the benefit this would have to each individual, the cost reduction in terms of preventing costly interventions necessary in case of osteoporosis development is a significant contribution.
