Retrieve user profile information ?

Hello,
I would like to know how it is possible to retrieve information present in the profiles of the users.
For example, gender, date of birth ...

I was thinking of something like:

<?php

	$idTarget = 984; // pour tests

	require_once(JPATH_ADMINISTRATOR . '/components/com_easysocial/includes/easysocial.php');

	$profil = ES::user($idTarget);

	$genreText = $profil->user->getFieldValue('gender');

	echo $genreText;	

?>

Best regards.

Eric
